MAX7451 - Video-Signal Conditioners

Download the MAX7451 datasheet PDF. This datasheet also covers the MAX7450 variant, as both devices belong to the same video-signal conditioners family and are provided as variant models within a single manufacturer datasheet.

General Description

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 ±6dB, detect fault conditions, and filter out-of-band noise.

Key Features

  • a user-adjustable clamp level. 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. Features.
  • Back-Porch Clamp to GND (MAX7450/MAX7451).
  • Adjustable Back-Porch Clamp (MAX7452).
  • Automatic Gain Control (±6dB Range) Normalizes Signals to Standard Video Level.
  • Input Fault Detection with LOS Output.
  • Inherent 50Hz/60Hz Input Rejection of 60dB.
  • Sing.

The devices restore the DC level of the video input, correct for amplitude errors up to ±6dB, 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 +6dB) and an AGC-disable function.
