@ Pin Function
pins (YA-Y3) as 8-bit digital data.
L: normal mode
INSL
L: analog input
11 | OCLK
Clock amplifier input
(Inputs clock that has a DC cut at capacitor by 0.8 Vp-p or more)
12 [DVa | — | Digital ground
P13 [DVoo | = _| Digital power supply (SV)
Input switching, switches input of comb filter.
| 14 | CLKO
| 0 | Clock amplifier output
15 | MCK
I__|
Clock input (inputs 4 fsc clock, that is locked to color burst).
Normaily connected to pin 14 clock amplifier output.
16 | ADCK
Clock input for A/D converter (inputs same clock as MCK).
Normally connected to pin 14 clock amplifier output.
17 | CLPI
Clamp pulse input for A/D converter.
Clamps signal voltage between low blocks of clamp pulse
(connected to DVpo when clamp function is "OFF').
18 | XCPON
H: clamp function becomes "OFF", has normal A/D converter function only.
L: clamp function operates
19 | ADVS
Pee Digital ground for A/D converter
20 | ICP
I | Voltage integration pin for clamp control, connected to about a 0.01 uF capacitor
(connected to ground if clamp is not used).
21 | CRV
Clamp reference voltage input. Equalizes reference voltage and input voltage of
clamp block (connected to ground if clamp is not used).
