Chapter 17
Audio Interface Module (AIM)
This chapter discusses the audio interface structure, memory map, and register descriptions, as well as
transmit and receive interfaces.
17.1
Audio Interface Overview
The audio interface module provides the necessary input and output features to receive and transmit digital
audio signals over serial audio interfaces (IIS/EIAJ) and over digital audio interfaces (IEC958).
2
The MCF5253 is equipped with three serial audio interfaces compliant with Philips I
S and Sony EIAJ
format. There are two IEC958 (SPDIF) receivers with 4 multiplexed inputs, and one IEC958 (SPDIF)
transmitter with two outputs: One for professional C-channel and one for consumer C-channel.
The audio interface module allows the direct retransmission of an audio signal received on one receiver to
another transmitter, without CPU intervention, or it allows the CPU to receive or transmit digital audio to
or from any of the audio interfaces.
The IEC958 (SPDIF) receivers and transmitter support audio and allow the handling of IEC958 C and
U channels.
A frequency measurement block exists to allow precise measurement of an incoming sampling frequency.
This can be used in conjunction with the XTRIM output (and with the appropriate control software) to
“lock” the clock that is being input to CRIN (either external generated clock or crystal) to the recovered
SPDIF audio clock, if so desired. Some external hardware is required for this including a set of varicap
diodes. This is covered in
Section 17.9, “Phase/Frequency Determination and XTRIM Function.”
