Description
Standard open voltag
13
Antenna switch
When pin 13 is connected
to V
CC
, RF oscillator and
driver changeover pin are
operated and when this pin
is open circuited, RF oscilla-
tor is stopped.In this state, no
pop noise will not be made
when antenna switch is
turned on/off even if sound
system is operating.
0.7 V
14
Antenna switch
driver pin
When pin 13 is connected to
V
CC
, this pin voltage becomes
4.0 V. (RF oscillator ope-
rates
and load current is 15
mA)
When pin 13 is open-cir-
cuited, this pin voltage is 0 V.
(RF oscillator stops)
Drive capability of driver pin
is approx. 30 mA.
Pin 13: V
CC
4.0 V
(Load cureent in 15 mA)
Pin 13: Open
0 V
15
RF output pin
Output pin of RF signal.
It has low impedance output.
2.7 V
16
Video input pin
The sync. peak value
clamp
system is adopted for input
clamp circuit. This pin has a
high input impedance to
minimize sync. distortion.
Pay attention to the sync. sag
which is likely to occur when
an external capacitor attached
is 0.47
μ
F or less.
