Description
The CDB4244 evaluation board is an excellent platform
designed to facilitate evaluation of the CS4244 multi-
channel CODEC. Use of the board requires an ana-
log/digital signal source, an audio analyzer, and power
supplies. A Windows
PC-compatible computer is also
needed in order to configure the board.
System timing for the I²S and Left-Justified serial inter-
face formats can be accomplished using S/PDIF I/O or
crystal-based timing hardware on the CDB4244. An ex-
ternal DSP interface header supports I²S, Left-Justified,
and TDM serial interface formats.
1/8” audio jacks, three-pin headers, and RCA phono
jacks are provided for the CS4244 analog I/O connec-
tions. Digital I/O connections are accomplished through
RCA phono jacks or optical connectors leading to the
S/PDIF receiver and transmitter.
The Windows-based software available online makes
configuring the CDB4244 easy. The software commu-
nicates through the PC’s USB port to control the
CS4244, the S/PDIF receiver and transmitter, and the
clock synthesizer. These devices can also be con-
trolled through an external control header for easy in-
system evaluation.
