Description
The CDB4228A evaluation board is an excellent means
for quickly evaluating the CS4228A 2 in, 6 out, 24-bit,
96kHz capable CODEC. Evaluation requires an analog
signal source and analyzer, a digital signal source and
analyzer, a PC compatible computer for control, and a
power supply.
System timing can be supplied by the CS8414 digital au-
dio receiver I.C., or an onboard oscillator. Control is
provided by PC software. The evaluation board may also
be configured to accept external timing, data, and control
signals for operation in a user application during system
development.
