MAX7445 Datasheet 4-channel Video Reconstruction Filter

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-2948; Rev 1; 10/05 4-Channel EVAALVUAAILTAIOBNLEKIT Video Reconstruction Filter MAX7445.

General Description

The MAX7445 4-channel, buffered video reconstruction filter is ideal for anti-aliasing and DAC-smoothing video applications or wherever analog video is reconstructed from a digital data stream (such as cable/satellite/terrestrial set-top boxes, DVD players, hard-disk recorders (HDRs), and personal video recorders (PVRs)).

This device operates from a single +5V supply and has a flat passband out to 5MHz with a stopband attenuation of 43dB at 27MHz.

This makes it ideal for use with NTSC, PAL, and standard-definition digital TV (SDTV) video systems.

Key Features

  • 4-Channel Filter and Buffer for CVBS, RGB, or Y/C Video Signals.
  • Filter Response Ideal for NTSC, PAL, and Interlaced SDTV Video Signals.
  • 43dB (typ) Stopband Attenuation at 27MHz.
  • ±0.75dB (max) Passband Ripple Out to 5MHz.
  • Blanking Level Voltage on Cable.
