Technical Summary

This technical summary provides a brief description of the MCD221

CD–Interface and Audio Processor. A complete data sheet for the MCD221 is

available and can be ordered from your local Motorola sales office. The order

number is MCD221/D.

QFP PACKAGE

CASE 841B–01

The MCD221 has two main functions. The first is to form an interface

between a CD drive unit and a CD–i or Photo–CD player. The connection to the

drive is designed for both applications and can be either a Digital Out (EBU

either a 68000 interface for CD–i players, or a serial (SPI) interface for

Photo–CD.

The second function of the MCD221 is to decode ADPCM (CD–i base case)

audio, to perform audio mixing functions as specified in the Green Book, and to

be able to add external audio to the base case audio. The MCD221 can also be

used for handling the ADPCM decoding for Photo–CD.

The main features of the MCD221 are as follows:

•

Accepts Audio Inputs in I S Format (MPEG1) for Mixing with CIAP Internal

Audio

•

Output Can Be Either I S or SONY Format

Data Input Rate Can Be Up to 2 Times Normal Speed

Can Connect to a Host via Either a 68K or Serial Interface

80–Pin Quad Flat Pack (QFP)
