General Description
The CDB4226 is useful for evaluating the performance
of the CS4226. Up to three stereo input sources can be
connected to the evaluation board, one of which is se-
lected for A/D conversion. Six channels of D/A
conversion allow for multi-channel applications such as
Dolby Pro-Logic, Dolby Digital (AC-3), THX, and DSP-
based soundfield applications. S/PDIF I/O support is
provided by the CS4226’s on-chip S/PDIF receiver and
a CS8402A S/PDIF transmitter. For serial audio connec-
tions, access to the part’s auxiliary and DSP ports is also
provided. The board can be configured and controlled
by a peripheral serial control port. The peripheral control
options are SPI and I²C. PC software which supports the
board's SPI interface is provided, and can be used to set
the internal control registers of the CS4226.
