Description
The ZiLOG ZHX2010 is an ideal side-look transceiver for applications in today's
ultracompact power-conscious portable products, such as notebook PCs, mobile
phones, digital cameras, portable printers, handheld computers, or personal data
assistants (PDAs). Designed to support all IrDA at up to 4 Mb/s and LocalTalk
TM
and Sharp ASK
TM
modes, the transceiver combines an infrared emitting diode
(IRED) emitter, a PIN photodiode detector, a programmable LED driver, and a dif-
ferential receiver in a single, miniature package.
The ZiLOG ZHX2010 provides an efficient implementation of the IrDA-Data 1.4
standard in a small footprint format. Application circuit space is also minimized, as
only two external components (a terminating resistor and a decoupling capacitor)
are required to implement a complete IrDA transceiver solution.
The ZHX2010 is capable of legacy-mode power management and bandwidth
switching.

TXD Transmit Data
(Input, active high)
This CMOS input is used to transmit serial data when SD is low. An on-chip
protection circuit disables the IRED driver if the TX pin is asserted for longer than
100
s. When used in conjunction with the SD pin, this pin also provides control
signals to the internal digital serial control interface and legacy mode subsystems.
This input has an internal pull-down resistor that is disabled (open-circuited) dur-
ing shutdown. TXD has integrated digital AC coupling that prevents inadvertent
"always on" IREDs; therefore, no external AC coupling components are required
for input signals between GND and V
CC
.
RXD Receive Data
(Output, active low)
This output indicates received serial data. It is a push-pull CMOS driver capable of
driving a standard CMOS or TTL load. No external pull-up or pull-down resistor is
required.
SD Shutdown
(Input, active high)
This CMOS input pad functions as a shutdown switch and as a mode switch,
allowing bandwidth changes.
Shutdown and Legacy Mode Bandwidth Switching
Assertion of this pin high for a period of time exceeding 500 m places the module
into legacy shutdown mode, reducing current consumption to ~50 nA. On the fall-
ing edge of this signal, the state of the TX pin is sampled and used to set receiver
low bandwidth (TX = Low) or high bandwidth (TX = High) mode.
The transceiver powers on with the upper limit of the receiver bandwidth set to
1.152 Mbits/s operation. To set the bandwidth for operation at 4 Mbits/s, apply the
timings shown in Figure 3 to the SD and the TX inputs.

Figure 3. Timings for 4 Mbit/s Bandwidth Operation
The internal LED driver is disabled when SD is active and is not
enabled until the next rising edge of TX. This ensures that the
LED is not active during bandwidth adjustment.
It is recommended that the SD pin be connected to GND if the bandwidth adjust-
ment and shutdown modes are not required.

Packing, Storing, and Baking Recommendations
Follow these recommendations to maintain the performance of the ZHX2010
transceiver.
Storage
To avoid moisture absorption, ZHX2010 reels must remain in the original,
unopened moisture-proof packing. Parts must be soldered within 48 hours after
unpacking. Reels that have been unpacked, but will not be soldered within 48
hours, must be stored in a desiccator.
Baking
Parts that have been stored over 12 months or unpacked over 48 hours must be
baked under the following guidelines.
Reels
60 C for 48 hours or more
Loose Parts
100 C for 4 hours or more
or
125 C for 2 hours or more
or
150 C for 1 hour or more
ZHX2010

Moisture-Proof Packing
In order to avoid moisture absorption during transportation and storage, ZHX2010
reels are packed in aluminum envelopes (see Figure 9) that contain a desiccant
with a humidity indicator. The indicator changes color from blue to pink as mois-
ture is absorbed.
