for the MAX7450/MAX7452. Connect +3.3V to V
CC
for the MAX7451. Bypass to GND with 1μF and 0.1μF capacitors as close to the pin as possible.

SS
Negative Power Supply. Connect -5V to V
SS
for the MAX7450. Connect -3.3V to V
SS
for the
MAX7451. Bypass to GND with 1μF and 0.1μF capacitors as close to the pin as possible.

BPLVL
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
BPLVL
/1.5.

AGCD
Automatic Gain-Control Disable Input. Disable AGC by driving AGCD to V
CC
. Enable AGC by
driving AGCD to GND.

GSET
Gain-Setting Input. Drive GSET high to set buffer gain to +6dB. Drive GSET low to set buffer
gain to 0dB.

LOS
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.

EP
Exposed Pad. Connect to V
SS
(MAX7450/MAX7451). Connect to GND (MAX7452).
