Bidirectional Video Filters/Buffers for Composite

and S-Video Portable Media Devices

1/MAX7482

General Description

Features

The MAX7481/MAX7482 bidirectional video filters/

buffers provide the reconstruction filter and line drive

buffer for both composite (CVBS) and S-Video (Y/C)

video signals in playback mode, and anti-aliasing in

record mode for portable media devices. Each channel

consists of a lowpass filter and an output buffer capa-

♦ Composite and S-Video, Video-Playback and Video-

Record Interface for Portable Video Devices

♦ Saves Space by Sharing Connectors in Portable

Devices

♦ DirectDrive

Eliminates Expensive AC-Coupling Capacitors

Blanking Level at Ground with Single Supply

ble of driving a full 2V

video signal into one standard

P-P

150Ω load (DC-coupled to ground). In record mode,

the MAX7481/MAX7482 output buffers have a gain of

+6dB. In playback mode, the MAX7481 output buffers

have a gain of +6dB and the MAX7482 output buffers

have a gain of +7dB.

♦ Composite and Y/C Signals

♦ Advanced Power-Down Modes for Extended

Battery Life

♦ Low Supply Current in Shutdown Mode, < 1µA (typ)

♦ Filter Response Ideal for NTSC and PAL

♦ +6dB (MAX7481) or +7dB (MAX7482) Gain

♦ +2.7V to +3.6V Single-Supply Operation

♦ Small, 28-Pin, TQFN Package (5mm x 5mm)

Ordering Information

The MAX7481/MAX7482 feature DirectDrive™ by utilizing

an internal negative charge pump and regulator to main-

tain the output blanking level at ground, eliminating the

need for a negative supply voltage, a large output cou-

pling capacitor, or a sag correction configuration.

The MAX7481/MAX7482 operate from a single +2.7V to

+3.6V power supply. These devices are available in a

space-saving 28-pin TQFN package and operate over

the -40°C to +85°C extended temperature range.
