Description
The CDB42L55 is the ideal evaluation platform solution to test
and evaluate the CS42L55.The CS42L55 is a highly integrat-
ed, 24-bit, ultra-low-power stereo CODEC based on multi-bit
Delta-Sigma modulation suitable for low-power portable sys-
tem applications. Use of the board requires an analog or digi-
tal signal source, an analyzer, and power supplies. A
Windows PC-compatible computer is also needed in order to
configure the CS42L55 and the board.
System timing can be provided by the CS8416 S/PDIF Re-
ceiver, by the CS42L55 supplied with a master clock, or via an
I/O stake header with a DSP connected.
RCA connectors are provided for CS42L55 analog inputs and
HP/Line outputs. A 1/8 inch audio jack is provided for head-
phone stereo out. Digital I/O connections are available via
RCA phono or optical connectors to the CS8416 and CS8406
(S/PDIF Rx and Tx).
The CDB42L55 is programmed via the PC’s USB using Cirrus
Logic’s Microsoft ? Windows ? -based FlexGUI software. The
evaluation board may also be configured to accept external
timing and data signals for operation in a user application dur-
ing system development.
