Block Operation Descriptions
The following describes the operation of each
block and external circuits.
Video Clamp
The video clamp circuit employs a sync peak value
clamp. Input impedance is at a level of
approximately 30 k
to reduce compression of the
sync pulse. Note that sag is generated in the sync
pulse when a capacitor of 0.47 F or lower is used
for C10 at pin 16.
Figure 1 Video Input Circuit
White Clip Circuit
The white clip level is set to 92.5%. A circuit that
produces a sharp white clip is used in order to
produce high linearity characteristics for the video.
Increasing the white clip frequency characteristic
by another 5 MHz eliminates video carrier cutoff
by the chroma signal and prevents deterioration of
audio buzz characteristics.

RF Oscillator/Channel Switch
A new type RF oscillator is employed to reduce RF
harmonics to a level that is dramatically lower than
previous available Hitachi products.
Note that using a capacitor lower than 0.22 F at
pin 3 causes an increase in sync pulse sag.
The input resistance at pin 11, which is the
oscillator input pin, is 3 k
. Pins 9 and 10 are
oscillator output pins, and are NPN transistor
emitter-follower types.
The oscillator frequency is selectable by switching
the pin 7 channel switch between SAW resonator
low channel and high channel. When the channel
switch is open, oscillation output is performed
from pin 9, while grounding the switch causes
output from pin 10. The switching voltage of the
channel switch is approximately 2.1 V. When the
channel switch is grounded, a current of 30 A
flows through pin 7, which is sufficient to drive an
electronic switch.
Antenna Switch
The antenna switch links the drive circuit that
switches the RF switch on and off with the chip's
Figure 3 RF Oscillator Interface Circuit
RF oscillator on/off operation.
Opening the switch at pin 13 stops oscillation of
the RF oscillator and the antenna switch drive
output at pin 14 becomes 0 V. The audio system is
operating in this state, which acts to suppress
generation of popping noise in the audio as the
antenna switches between on and off.
When pin 13 is connected to V
CC
by a closed
switch, the RF oscillator is operational and the
antenna switch drive output DC level at pin 14 is
high.
Pin 13 should be connected to V
CC
when the
antenna switch is not used. A maximum current of
30 mA can be obtained from the antenna switch
driver.
Be sure to connect 10 k
for R3 at pin 13 when
the antenna switch is being used. R2 is used as
protective resistance when the antenna switch
power supply is switched on before the chip power
supply.

Audio Modulator
Pins 4 and 5 make up the reference oscillator for
the 4.5 MHz audio modulator. Pin 4 is the
oscillator 's reference bias source. A 15 pF
capacitor must be used for C3 at pin 4 to cut the ac
signal. The oscillation frequency is determined by
an external tank circuit.
Figure 5 Audio Modulator Interface Circuit
An external cuppling capacitor is not required
when pin 6, which is the audio input pin, is almost
equal to ground potential and the audio input
signal dc level is ground potential. The ground
potential of the input pin results in a circuit
configuration that reduces pin 6 voltage
fluctuations and suppresses popping noise.
