NAME
FUNCTION
11
VCC
Positive Power Supply. Connect +5V to VCC for the MAX7450/MAX7452. Connect +3.3V to VCC
for the MAX7451. Bypass to GND with 1F and 0.1F capacitors as close to the pin as possible.
2
IN
Video Input. AC-couple video signal through a 0.1F capacitor.
33
GND
Ground
4—
VSS
Negative Power Supply. Connect -5V to VSS for the MAX7450. Connect -3.3V to VSS for the
MAX7451. Bypass to GND with 1F and 0.1F capacitors as close to the pin as possible.
—4
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 VBPLVL/1.5.
55
AGCD
Automatic Gain-Control Disable Input. Disable AGC by driving AGCD to VCC. Enable AGC by
driving AGCD to GND.
66
OUT
Video Output
77
GSET
Gain-Setting Input. Drive GSET high to set buffer gain to +6dB. Drive GSET low to set buffer
gain to 0dB.
88
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 VSS (MAX7450/MAX7451). Connect to GND (MAX7452).
