Description
The CDB5345 evaluation board is an excellent means
for evaluating the CS5345 ADC. Evaluation requires an
analog signal source and analog/digital analyzer, and
power supplies. A Windows
must be used to evaluate the CS5345.
System timing for the I²S, Left-Justified and Right-Justi-
fied interface formats can be provided by the CS5345,
the CS8406, or by a PCM I/O stake header with an ex-
ternal source connected.
RCA phono jacks are provided for the CS5345 analog in-
puts and outputs. Digital data input is available via RCA
phono or optical connectors to the CS8406.
The Windows
uration
communicates through the PC’s serial port to configure
the control port registers so that all features of the
CS5345 can be evaluated. The evaluation board may
also be configured to accept external timing and data
signals for operation in a user application during system
development.

... The FPGA handles both clock and data routing on the CDB5345. Clock and data routing selections made via the CDB5345 Controls tab in the GUI will be handled by the FPGA with no user intervention required. For advanced information regarding the internal registers and operation of the FPGA, see sections 4 and 5 beginning on page 10 ...

... SYSTEM CLOCKS AND DATA The CDB5345 implements comprehensive clock routing capabilities. Configuration of the clock routing can be easily achieved using the controls within the Board Controls group box on the CDB5345 Controls tab in the GUI software application. 2.1 Clock Routing The master clock signal (MCLK) may be sourced from the canned oscillator (Y1) or the PCM1 I/O header ...

... The CDB5345 Controls tab provides a high-level intuitive interface to many of the configuration options of the CS5345 and CDB5345. The controls within the ADC/PGA Controls group box control the internal regis- ters of the CS5345. The controls within the Board Controls group box control the board level clock and data routing on the CDB5345 ...

... CS5345 input multiplexer will be digitized by the ADC and transmitted in S/PDIF format by the CS8406. No signal will be output through the active output filter and RCA jacks. The canned oscillator is the source of MCLK. The CS5345 is the sub-clock master to the CS8406 and the PCM1I/O header. DS658DB1 CDB5345 9 ...
