Analog Outputs
The CS4270 analog outputs are AC-coupled and routed through a single-pole RC Low-Pass filter.
Control Port
A graphical user interface is included with the CDB4270 to allow easy manipulation of the registers in the
CS4270 (see the CS4270 data sheet for register descriptions and the
page
or an RS-232 cable to J16 and launching the Cirrus Logic FlexGUI software enables control and configura-
tion of the board.
