Video-Signal Conditioners with AGC and  
Back-Porch Clamp  
General Description  
Features  
Back-Porch Clamp to GND (MAX7450/MAX7451)  
Adjustable Back-Porch Clamp (MAX7452)  
The MAX7450/MAX7451/MAX7452 complete front-end  
video-signal conditioners are designed to improve the  
quality of standard-definition video signals. The devices  
restore the DC level of the video input, correct for  
amplitude errors up to ±±dꢀ, detect fault conditions,  
and filter out-of-band noise. The MAX7450/MAX7451/  
MAX7452 optimize the signal quality for further video  
processing through a crosspoint switch or video  
decoder (ADC). Each device integrates an input video  
clamp, automatic gain control (AGC), loss-of-sync  
(LOS) detector, and an out-of-band noise/lowpass filter.  
These devices also incorporate a user-selectable  
buffer gain (0 or +±dꢀ) and an AGC-disable function.  
Automatic Gain Control (±±dB ꢀanꢁe) Normaliꢂes  
Siꢁnals to Standard Video Level  
Input Fault Detection with LOS Output  
Inherent 50Hꢂ/±0Hꢂ Input ꢀejection of ±0dB  
Sinꢁle-Supply Operation: MAX7452 (+5V)  
Out-of-Band Noise Filter  
Output Buffer Drives Standard 150 Video Load  
with 0dB or +±dB Gain  
The MAX7450 and MAX7451 operate from dual power  
supplies of ±5ꢁ or ±.ꢂꢁ respectively, and they restore  
the video blanking level to GND. The MAX7452 operates  
from a single +5ꢁ supply and features a user-adjustable  
clamp level.  
Dual-Supply Operation  
MAX7450 (±5V)  
MAX7451 (±ꢃ3ꢃV)  
Tiny 8-Pin SO Packaꢁe  
The devices are available in an 8-pin SO package with  
an exposed pad and are specified for operation over  
the extended (-40 C to +85 C) temperature range.
