W682510/W682310
1. GENERAL DESCRIPTION
The W682510 and W682310 are general-purpose dual channel PCM CODECs with pin-selectable
-
Law or A-Law companding. The device is compliant with the ITU G.712 specification. It operates from
a single power supply (+5V for the W682510, +3V for the W682310) and is available in 20-pin PDIP
(W682510 only), SSOP, and 24-pin SOP package options. Functions performed include digitization
and reconstruction of voice signals, and band limiting and smoothing filters required for PCM systems.
The filters are compliant with ITU G.712 specification. The W682510 and W682310 performance is
specified over the industrial temperature range of 40
C to +85
C.

The W682510 includes an on-chip precision voltage reference and receive output buffer amplifiers,
capable of driving 600
loads (line transformers.) The analog section is fully differential, reducing
noise and improving the power supply rejection ratio. The data transfer protocol supports either
parallel or serial synchronous communications for PCM applications. The W682510 and W682310
have a build in PLL that eliminates the need for a master clock and automatically determines the
division ratio for the required internal clock.

For fast evaluation and prototyping purposes, the W682510DK & W682310DK development kits are
available.

W682510/W682310
7. FUNCTIONAL DESCRIPTION
W682510/W682310 is a single-rail, dual channel PCM CODEC for voiceband applications. The
CODEC complies with the specifications of the ITU-T G.712 recommendation. The CODEC includes
two complete
-Law and A-Law companders. The
-Law and A-Law companders are designed to
comply with the specifications of the ITU-T G.711 recommendation.

The block diagram in section 3 shows the main components of the W682510/W682310. The chip
consists of a PCM interface, which can process the data in parallel or serial formats. The PLL of the
chip provides the internal clock signals and synchronizes the CODEC sample rate with the external
frame sync frequency. The power-conditioning block provides the internal power supply for the digital
and the analog section, while the voltage reference block provides a precision analog ground voltage
for the analog signal processing.

ATH
The A-to-D path of the CODEC contains an analog input amplifier with externally configurable gain
setting (see application examples in section 11). The transmit amplifier output is the input to the
encoder section.
The output of the input amplifier is fed through a low-pass filter to prevent aliasing at the switched
capacitor 3.4 kHz low pass filter. The 3.4 kHz switched capacitor low pass filter prevents aliasing of
input signals above 4 kHz, due to the sampling at 8 kHz. The output of the 3.4 kHz low pass filter is
filtered by a high pass filter with a 200 Hz cut-off frequency. The filters are designed according to the
recommendations in the G.712 ITU-T specification. From the output of the high pass filter the signal is
digitized. The signal is converted into a compressed 8-bit digital representation with either
-Law or A-

Law format. The
-Law or A-Law format is pin-selectable through the
/A-Law pin. The compression
format can be selected according to Table 7.1.

7.1.1. AI1, AI2, AO1-, AO2-
AI1 and AI2 are the transmit analog inputs for channels 1 and 2. AO1- and AO2- are the transmit level
feedback for channels 1 and 2. AI1 and AI2 are inverting inputs for the Op-Amps. AO1- and AO2- are
connected to the outputs of the Op-Amps and are used to set the level, as illustrated below. When AI1
and AI2 are not used, connect AI1 to AO1- and AI2 to AO2-. During power saving mode and power
down mode, the AO1- and AO2- outputs are tied weakly to V
SSA
on the W682510 or are high
impedance on the W682310 (See table on page 14).

sent from PCMT1 in a sequential order, synchronizing with the rising edge of the BCLK signal. The
MSB may be output at the rising edge of the FST signal, based on the timing between BCLK and FST.
This output pin is in a high impedance state except during 8-bit PCM output. It is also in a high
impedance state during power-saving state or power-down. When serial operation is selected, this pin
is configured to be the output of the serial multiplexed two channel PCM signal. A pull-up resistor must

MSB may be output at the rising edge of the FST signal, based on the timing between BCLK and FST.
This pin is in a high impedance state except during 8-bit PCM output. It is also in a high impedance
state during power-saving state or power-down. When the serial operation is selected, this pin is left
open. A pull-up resistor must be connected to this pin , as it is an open drain output. This device is

7.2. R
ECEIVE
P
ATH
The 8-bit digital input samples for the D-to-A path are serially shifted in by the PCM interface and
converted to parallel data bits. During every cycle of the frame sync FSR, the parallel data bits are fed
through the pin-selectable
-Law or A-Law expander and converted to analog samples. The mode of
expansion is selected by the
/A-Law pin as shown in Table 7.2. The analog samples are filtered by a
low-pass smoothing filter with a 3.4 kHz cut-off frequency, according to the ITU-T G.712 specification.
A sin(x)/x compensation is integrated with the low pass smoothing filter. The output of this filter is
buffered to provide the receive output signal RO.
7.2.1. RO1, RO2
RO1 and RO2 are the receive analog outputs for channel 1 and channel 2. The output signal of the
W682510 has an amplitude of 3.46 Vpp (2.03 Vpp for W682310) around the signal ground voltage
(V
REF
). When the digital PCM signal of +3 dBm0 is presented to PCMR1 or PCMR2, it can drive a load
of 600 Ohms or more at 5 V supply voltage for the W682510 and 1200 Ohms at 3V supply for the
W682310. During power saving mode, these outputs are at the voltage level of V
REF
with a high
impedance. These outputs have a feature that reduces audio "pop" noises when switching between
active and inactive states and back.

W682510/W682310
7.2.2. PCMR1
The PCM signal input for channel 1 when in the parallel mode. D/A conversion is performed on the
serial PCM signal input to this pin. The FSR signal, synchronous with the serial PCM signal, and the
BCLK signal, processes the code. Then the analog output is output from the RO1 pin. The data rate of
the PCM signal is equal to the frequency of the BCLK signal.
The PCM signal is shifted in on the falling edge of the BCLK signal. It is latched into the internal 8-bit
register. The start of the PCM data (MSB) is synchronized with the rising edge of FSR. In the serial
mode, this pin is not used and should be connected to GND (0V).
7.2.3. PCMR2
PCM signal input for channel 2 when the parallel mode is selected. D/A conversion is performed with
the serial PCM signal input to this pin, the FSR signal, synchronous with the serial PCM signal, and
the BCLK signal, and then the analog output is output from the RO2 pin. The data rate of the PCM
signal is equal to the frequency of the BCLK signal. The PCM signal is shifted at the falling edge of the
BCLK signal and latched into the internal register when shifted by eight bits. The start of the PCM data
(MSB) is identified at the rising edge of FSR. In the serial mode this pin is used for the two channel
multiplexed PCM signal input.

DD
The power supply for the analog and digital parts of the W682510 must be 5V +/- 10% and 2.7V to
3.8V for the W682310. This supply voltage is connected to the V
DD
pin. The V
DD
pin needs to be
decoupled to ground through a 0.1
F ceramic capacitor. A power supply for an analog circuit in the
system to which the device is applied should be used. A bypass capacitor of 0.1 F to 1 F with good
high-frequency characteristics (Low ESR) and a capacitor of 10 F to 20 F should be connected
between this pin and the V

pin on the printed circuit board to make a common ground.
However, it's advised to connect the PCB traces of these pins at the main supply hookup of the PCB
and run the V
SSA
and V
SSD
traces separately to the device

7.3.4. V
REF
This pin carries the signal ground voltage level and requires a bypass capacitor. A 0.1
F ceramic
(with low ESR for good high frequency response) capacitor needs to be connected between the V
SSA
pin and the V
REF
pin.
7.3.5. PUI
Power up input signal. When the PUI pin is set to logic "0" level, the CODEC will go into power down
mode.
7.4. PCM I
NTERFACE
The PCM interface is controlled by pins PCMMS, BCLK, FSR & FST. The input data is received
through the PCMR pin and the output data is transmitted through the PCMT pin. The modes of
operation of the interface are shown in Table 7.2.

/A-Law
This pin selects the desired companding law. The CODEC will operate in the
-law when this pin is at
a logic "0" level and in the A-law when at a logic "1" level. The CODEC operates
-law if the pin is left
open, since this pin is internally pulled down.

7.4.2. BCLK
This is the shift clock signal input for the PCMR1, PCMR2, PCMT1, and PCMT2 signals. The
frequency, equal to the data rate, is 64, 96, 128, 192, 256, 384, 512, 768, 1024, 1536, 1544, 2048 or
200 kHz. Setting this signal to a steady logic "1" or "0" sets both transmit and receive circuits to the
power saving state.
7.4.3. FSR
This is the receive synchronizing signal input. The required eight-bits of PCM data are selected from
the PCM data signal to the PCMR1 and PCMR2 pins by the receive synchronizing signal. All timing
signals in the receive section are synchronized by this synchronizing signal. This signal must be in
phase with the BCLK. The frequency should be 8 kHz
50 ppm to guarantee the AC characteristics.
This device can operate in the range of 6 kHz to 9 kHz, but the electrical characteristics specified in
the data sheet are not guaranteed.
7.4.4. FST
The transmit synchronizing signal input. The PCM output signal from PCMT1 and PCMT2 is sent in
synchronization with this transmit synchronizing signal. This FST signal triggers the PLL and
synchronizes all timing signals of the transmit section. The synchronizing signal must be in phase with
BCLK. The frequency should be 8 kHz
50 ppm to guarantee the AC characteristics. This device can
operate in the range of 6 kHz to 9 kHz sample rates, but the electrical characteristics are not
guaranteed. Setting this signal to logic HIGH or LOW drives both transmit and receive circuits to
power saving state.
7.4.5. PCMMS
The control signal for mode selection of the PCM input and output. When this signal is HIGH, the PCM
input and output are in the parallel mode. The PCM data of CH1 and CH2 is input to PCMR1 and
PCMR2, and output from PCMT1 and PCMT2, with the same timing. When this signal is at a LOW
level, the PCM input and output are in the serial mode. The PCM data of CH1 and CH2 is input to
PCMR2 and output from PCMT1 as two serial 8-bit bytes.

7.5.1. Power Save Mode
In the power save mode, all internal analog circuits except the internal reference are powered down.
The CODEC automatically enters the power save mode when the FST or BCLK signal is set to digital
"1" or digital "0";
Upon power up with FST and BCLK signals present, it will take 2 to 10 milliseconds for the internal
PLL to lock. In addition to the PLL lock-in time, the analog outputs will be set to the internal signal
ground for 1 millisecond. This will avoid power up glitches at the outputs. The digital open drain
outputs will remain at high impedance during this power up delay.

Revision 0.35
W682510/W682310
7.5.2. Power Down Mode
When the power up indicator pin, PUI, is set LOW all internal circuits will go into the power down state.
It will take 2 to 10 milliseconds for the PLL to lock when operation is resumed with the FST and BCLK
signals applied and PUI set HIGH. An additional 1-millisecond delay is used to set the analog outputs
to the signal ground reference in order to avoid power up glitches. The digital open drain outputs will
remain at high impedance during this power up delay.
7.5.3. Power Save/Down Output pin state
