This document will concentrate on the features and basic operation of the CK49x board. Detailed
information regarding the operation and programming of the CS4953x4 DSP is covered by the CS4953xx
Data Sheet
, the CS4970x4/CS4953x4 System Designer’s Guide and the application note AN288. See
Section 1.4 “DS898CK4Other Useful Information” on page 1-14
for more details.
The CK49x is a convenient and easy-to-operate evaluation platform. It has been designed to demonstrate
the majority of the DSP functions on a 9" x 6.5" base board. These features include:
• PC control of the DSP using the DSP Composer
™
graphical user interface
• Serial control of audio devices on CK49x Evaluation System via I
2
C™ or SPI™ protocols
• Digital audio input of PCM or compressed data via optical or coaxial S/PDIF
• Digital audio input of PCM or compressed data via HDMI
• 2-channel analog audio input via the CS42528 audio codec
• 8-channel analog output through the CS42528 audio codec
• Digital audio output of PCM data via optical S/PDIF
• Digital audio output of PCM or compressed data via HDMI (feature not currently supported)
• Multi-channel digital audio input via P11 header (feature not currently supported)
• Separate input and output clocking domains to allow 1FS-to-2FS audio processing on the DSP
• DSP Memory expansion through external 16-Mbit SDRAM
• Fast boot –master boot of custom applications from 32 Mbit serial SPI Flash device.
• Microphone input with integrated amplifier for Intelligent Room Calibration (IRC) evaluation
• Supports all members of the CS495xxx/CS4970x4 family in the 128-pin LQFP package.
Note:
Not all features of the DSP are exercised on the CK49x. Evaluation System
