Single-Channel Video Reconstruction Filters

and Buffers

General Description

Features

The MAX7462/MAX7463 single-channel, standard-defini-

tion, integrated video reconstruction filters and buffers

are ideal for anti-aliasing and digital-to-analog smoothing

video applications or wherever analog video is recon-

structed from digital data (such as cable/satellite/terres-

trial set-top boxes and DVRs).

♦ Passband: -0.05dB at 5MHz

♦ Stopband: -43dB at 27MHz

♦ Selectable Gain: +6dB and +9.5dB (MAX7462)

♦ Output Disable (MAX7462)

The MAX7462 includes a disable function, which

places the output in a high-impedance state allowing

multiplexing of multiple output signals. It also has an

external gain control that sets the output buffer gain to

either +6dB or +9.5dB. The higher gain setting allows a

nal. The MAX7463 output buffer has a fixed gain of

+6dB.

The MAX7462/MAX7463 operate from a single +5V

supply and have a flat passband out to 5MHz with a

stopband attenuation of -43dB (typ) at 27MHz.

PACKAGE

These devices can drive two standard 150Ω AC-cou-

pled or DC-coupled video loads. The output black level

of the MAX7462/MAX7463 is less than 1V for DC-cou-

pled outputs.

The MAX7462 is available in an 8-pin µMAX^®package

and an 8-pin SO package. The MAX7463 is available in

an 8-pin SO package. All devices are specified over

the 0°C to +85°C temperature range.
