ADVANCE INFORMATION

Micronas

connected to the chroma (Video 2) A/D converter. The

signal must be AC-coupled.

Pins 72-75 – Video Input 1–4 (Fig. 4–11)

These are the analog video inputs. A CVBS or S-VHS

luma signal is converted using the luma (Video 1) AD

converter. The VIN1 input can also be switched to the

chroma (Video 2) ADC. The input signal must be

AC-coupled.

Pin 76 – Supply Voltage, Analog Component Inputs

Front-End VSUPAI

This pin is connected with 220 nF/1.5 nF/390 pF to

GNDAI

Pin 77 – Ground, Analog Component Inputs Front-End

GNDAI

Pin 78 – Reference Voltage Top VREF (Fig. 4–8)

Via this pin, the reference voltage for the analog compo-

nent A/D converters is decoupled. The pin is connected

with 10

µF/47 nF to the Analog Component Signal

Ground Pin.

Pin 79 – Fast Blank Input FB1IN (Fig. 4–10)

This pin is connected to the analog fast blank signal. It

controls the insertion of the RGB1/YCrCb1 signals. The

input signal must be DC-coupled.

Pin 80 – Signal GND for Analog Component Inputs

AISGND (Fig. 4–10)

This is the high quality ground reference for the compo-

nent input signals.
