PIN NAME
FUNCTION
I / O
INTERFACE
11 / 13
TEST
Shipment test mode switch or I
2
C bus setting reset pin.
When High, test mode, setting all I
2
C bus settings to 0.
Hold High for at least 100
s. Send I
2
C bus settings
when this pin is Low.
I
12 / 14
KILLER
Y signal comb function ON / OFF switch.
When High, comb OFF. When Low, comb ON. When
[data 3 : bit 0] is 1, used as vertical edge enhancement
circuit ON / OFF switch.
I
13 / 15
CKIN
Clock input pin. Pin 13 put a sine wave which is locked
to the frequency of the burst signal in the input video
signal. Amplitude is 300 mV p-p to 2 Vp-p. Input as high
an amplitude as possible without affecting peripheral
circuits.
I
14 / 17
FIL
Connect the APC filter in the 8 fsc PLL circuit.
15 / 18
VDD1
PLL power supply.
16 / 19
VSS1
ADC, DAC, and PLL GND (analog).
17 / 20
COUT
Outputs chrominance signal. External simple LPF for
clock elimination recommended.
