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.
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)
