Input
Main timing driver for digital audio link, both edges used internally for tim-
ing. Also functions as the source to the PLL for internal clock generation.
Framing signal for digital audio link, high time indicates left channel data
and low time indicates right channel data. FSYNC is sampled on the falling
edge of the SCLK input.
Primary output port serial data pin. This data is the CS4610 output stream
going to the CS423x DACs. SDOUT transitions on the rising edge of the
SCLK input.
Primary input port serial data pin. This data contains both CS423x ADC
data and the CS423x output data. SDIN is sampled on the falling edge of
the SCLK input.
Framing signal for external 4333 DACs, high time indicates left channel
data and low time indicates right channel data. LRCLK transitions on the
falling edge of the SCLK input.
Second and third output port serial data pins. These output streams are
the expanded output channels beyond the CS423x left / right pair. The
serial data on these pins transition on the falling edge of the SCLK input.
Note that this is a DIFFERENT SCLK edge than the one for the SDOUT
pin.
