3.2 CDB4270 GUI
Brief descriptions of the GUI tab views are provided below.
The CDB4270 Controls tab provides high-level control of the CS4270, FPGA (Board Controls) and S/PDIF
Tx and Rx devices. The “CS4270 Controls” group affects that device’s register settings. The “Board Con-
trols” group allows the user to select MCLK and sub-clock source/routing as well as CS4270 and CS8406
SDIN sources. The “S/PDIF Receiver” and “S/PDIF Transmitter” control groups allow the user to select data
formats, MCLK frequency and master or slave for each device. Reset push-buttons are also available along
with a “Comm Mode” select drop box for CS4270 communication mode format selection.
