Pin No.
Function
11 4.21MHz IN
LA7316A-N, 7316AM
Input/Output State
Input 1kΩ
Remarks
Pin for inputting 4.21MHz for main converter. No matching resistor
required.
12 kIL FILTER
13 4.21MHz OUT
14 SYNC IN/BGP OUT
Output 1kΩ
Color killer phase detector filter pin.
Subconverter output pin. Low spurious output because of
operational type. No filter matching resistor required.
Used for COMP, SYNC input/BGP output.
15 REC APC FILTER
SP-EP/LP (PB)
16 VCO TANK
17 2fsc OUT
18 XOUT
E.F
REC mode : REC APC detector filter pin
PB mode : When the current flows in, LP mode is entered.
Pin for external tank circuit for 160fH VCO OSC.
CCD drive clock 2fsc output pin. LC are connected for spurious
output and stray capacitance compensation. If no 2fsc output is
required, this pin is left open or connected to VCC.
Crystal OSC crystal drive output pin. Supplies fsc to servo circuit
through resistor.
19 XO IN
20
VCC
21 VIDEO IN
22 SW30 IN
SP· EP/LP (REC)
Input
1.5kΩ at REC mode
500Ω at PB mode
Input/Output 15kΩ
Base input
Signal which passed through crystal is applied. OSC is provided
separately for REC/PB mode. No free-running frequency
adjustment required at PB mode.
Power supply pin
Video signal is applied at REC mode.
By pulling up to VCC using 4.7kΩ and diode, APC loop at PB
mode can be supplied to phase detector from before comb filter.
SW30 input. Threshold is set to 1/2VCC. When lowest voltage of
pulse drops to 0.7V or less, SEP mode is entered ; and when
raised to 1.3V or greater, LP mode is entered.
23 PB 3.58MHz OUT
E.F
24 PB AMPLIFIER IN
Input 1.5kΩ
PB chroma output to be applied to YC-MIX circuit.
Signal which passed through comb filter is applied.
No.3090–4/5
