The number of channels can be set up in the control registers and
is dependent on the sample rate. As the sample rate increases, the
number of possible channels decreases.
? At 96 kHz, the AD1939 operates with a maximum of eight chan-
nels in each direction. At 96 kHz, all of the TDM channels are
used by all analog outputs, but there are still four extra input chan-
nels, two of which can be used by the digital inputs.
? At the 192 kHz sample rate, a maximum of four channels in each
direction can be used, meaning that four of the output channels
cannot be used. To run at 192 KHz with all ADCs and DACs in
TDM mode, the codec must run in dual-line TDM mode.
For more information about the AD1939 codecs, go to
http://www.ana log.com and search for AD1939.
Example programs are included in the EZ-Extender installation directory
to demonstrate how to configure and use the board's analog audio
interface.

ration Switches” on page 2-5 , “Power LED” on page 2-16 , and
“Connectors” on page 2-17 .
