MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MCD221TS/D MCD221 Technical Summary CDćInterface and Audio Processor (CIAP) This technical summary provides a brief description of the MCD221 CD- Interface and Audio Processor. A plete data sheet for the MCD221 is available and can be ordered from your local Motorola sales office. The order number is MCD221/D. 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 standard) interface, or an I2S plus subcode interface. The host interface can be 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 I2S Format (MPEG1) for Mixing with CIAP Internal Audio - Output Can Be Either I2S 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) FU SUFFIX QFP PACKAGE CASE 841B- 01 ORDERING INFORMATION MCD221FU QFP NOTE: Supply of this Video- CD IC does not convey an implied license under any patent right to use this IC in any Video- CD application.
