Part Matrix vs. Code Matrix for Broadcast-based Applications
If compressed data is delivered to the DSP (via I2S or LJ) according to the IEC61937 specification, this A Broadcast Application implies that data is either would actually no longer be considered a an Elementary Stream (ES) or Packetized "broadcast-based" application (with the exception of the AAST and AACT codes), regardless of the Elementary Stream (PES) format. final product's intended purpose. Data delivery is either: If the data delivery is IEC61937-packed AC-3, * Serial Bursty (Configure INPUTA3 and send MPEG Multichannel, MP3 or AAC, the designer data to the CDI port while monitoring should then refer to the "CS4932X/CS49330, Part CMPREQ throttle line to make sure that Input Matrix vs. Code Matrix for AVR/Outboard FIFO is not over/under-flowed. Decoder-based Applications" as this would now be * Parallel Bursty (Configure for INPUTA7 or considered an AVR-based application in regards to INPUTA8 and send data to the parallel port in the data delivery. This document is available from the Cirrus Logic website on the CS49300 Page. Motorola or Intel format).

"PES over I2S" (Typically, data can not be delivered via an I2S or Left-Justified input, for any standard release broadcast-based application code, with the exception of AC3N, which accepts "PES over I2S" which follows a proprietary patent-pending packing technique developed by Cirrus Logic, Inc. This technique allows for the DSP to perform the Audio/Video Synchronization in the system. Most standard release application codes listed in this document can be modified accept "PES over I2S" upon request in addition to the signing of a CWLA.)
All Broadcast-based applications follow these rules (except where noted): Expected CLKIN = 27 MHz (Oscillator Value). DSPCLK = Refer to AN162 (Sampling Frequency and Application Code Dependent). Standard Hardware Configuration: OUTPUTA2 (DSP Masters MCLK, SCLK and LRCLK). Refer to AN162 and its appendices for how to control Broadcast-based Standard Release Application Codes that run on the CS4931X and/or CS49330.

AACT - Multichannel MPEG-2 AAC decoder supporting IEC61937-packed AAC (LC, ADTS) input with up to 5.1 channel discrete output. While this code normally would be considered AVR-based application code, it expects a 27MHz Oscillator on CLKIN and was developed specifically for a TeraLogic reference design. PCM mixing via the DAI input port is available for sources that have an input that has a matched Fs (32kHz, 44.1kHz or 48kHz) to that of the decoded AAC stream. This code has a default of OUTPUTA0, where all other Broadcast-based codes default to OUTPUTA2. Additionally, an IEC60958 Lt, Rt output is supported from the AUDAT3/XMT958 pin. External SRAM is

PCMP - The PCMP application code is a SMPTE 302M decoder designed for broadcast applications where PCM is delivered in an MPEG2 transport stream PES packet. It provides support for AV synchronization, channel change, bitstream parameter reporting and PLL control, among other features offered in other broadcast-based application codes discussed in AN162. In addition, a mutually exclusive PCM passthrough application mode is available with the PCMP releases. This is similar to the AVRbased AC-3 code that is capable of passing PCM via I2S data delivery.
