Video-Signal Conditioners with AGC
SUPPLY
BACK-PORCH = 0V
Positive Power Supply. Connect +5V to V
for the MAX7451. Bypass to GND with 1µF and 0.1µF capacitors as close to the pin as possible.
Video Input. AC-couple video signal through a 0.1µF capacitor.
Ground
Negative Power Supply. Connect -5V to V
MAX7451. Bypass to GND with 1µF and 0.1µF capacitors as close to the pin as possible.
Back-Porch Level Input. When gain = 2V/V (GSET = 1), output back-porch level is equal to
BPLVL input. When gain = 1V/V (GSET = 0), output back-porch level is equal to V
Automatic Gain-Control Disable Input. Disable AGC by driving AGCD to V
driving AGCD to GND.
Video Output
Gain-Setting Input. Drive GSET high to set buffer gain to +6dB. Drive GSET low to set buffer
gain to 0dB.
Loss-of-Sync Logic Output. LOS is high when video sync is lost for more than 15 horizontal
lines. LOS goes low when video sync is present.
