Audio/Video Switch for Dual SCART Connectors

General Description

Features

The MAX4397 dual SCART switch matrix routes audio

and video signals between an MPEG encoder and two

external SCART connectors under I²C* control, and

meets the requirements of EN50049-1, IEC 933-1,

Canal+, and BskyB standards.

♦ Audio Outputs Drive 3V

RMS

♦ Clickless, Popless Audio Gain Control and

Switching

The video and audio channels feature input source

selection multiplexers, input buffers, and output buffers

for routing all inputs to selected outputs. The MAX4397D

audio encoder input is differential DC-coupled, while the

MAX4397S audio encoder input is single-ended AC-

coupled. Except for the MAX4397D’s audio encoder

input, all other inputs and outputs are AC-coupled with

internal DC-biasing set to predefined levels.

♦ AC-Coupled Video Inputs with Internal Clamp and

Bias

♦ DC-Coupled Video Outputs

♦ Composite Video Signal Created Internally from

Y/C Inputs

♦ Internal Video Reconstruction Filters Provide

The MAX4397 provides programmable gain control from

+5dB to +7dB in 1dB steps for Red, Green, and Blue

component video signals. All other video outputs have a

fixed +6dB gain. Additional features include an internal

Luma and Chroma (Y/C) mixer that generates a

Composite video signal (CVBS) to supply an RF

modulator output, and internal video reconstruction low-

pass filters with a cutoff frequency of 6MHz. The

MAX4397 TV audio channel features clickless switching

and programmable volume control from -56dB to +6dB in

2dB steps. The VCR audio output also has programmable

gain for -6dB, 0dB, or +6dB. The device also generates

monaural audio from left and right stereo inputs. All audio

-35dB at 27MHz

♦ Differential (MAX4397D) or Single-Ended

(MAX4397S) Audio Encoder Input

♦ Red/Chroma Switch for Bidirectional I/O

♦ I²C-Programmable RGB Gain from +5dB to +7dB

♦ I²C-Programmable Audio Gain Control from +6dB

to -56dB

♦ Meets EN50049-1, IEC 933-1, Canal+, and BSkyB

Requirements

Ordering Information

The MAX4397 operates with standard 5V and 12V

power supplies and supports slow-switching and fast-

switching signals. The I²C interface programs the

gain and volume control, and selects the input source

for routing.
