Bidirectional digital-audio output bit clock. SCLK can be an output that is derived from MCLK
to provide 32 Fs, 64 Fs, 128 Fs, 256 Fs, or 512 Fs, depending on the MCLK rate and the
digital-output configuration. SCLK can also be an input and must be at least 48Fs or greater.
As an input, SCLK is independent of MCLK. BIDIRECTIONAL - Default: INPUT
Bidirectional digital-audio output-sample-rate clock. LRCLK can be an output that is divided
from MCLK to provide the output sample rate depending on the output configuration. LRCLK
can also be an input. As an input LRCLK is independent of MCLK.
BIDIRECTIONAL - Default: INPUT
CMOS level output that contains a biphase-mark encoded (S/PDIF) or I
digital audio data which is capable of carrying two channels of PCM digital audio or an
IEC61937 compressed-data interface.
This output typically connects to the input of an RS-422 transmitter or to the input of an optical
transmitter. OUTPUT
Bidirectional digital-audio bit clock that is an output in master mode and an input in slave
mode. In slave mode, SCLKN1 operates asynchronously from all other CS493XX clocks. In
master mode, SCLKN1 is derived from the CS493XX internal clock generator. In either master
or slave mode, the active edge of SCLKN1 can be programmed by the DSP. For applications
supporting PES layer synchronization this pin can be used as STCCLK2, which provides a
path to the internal STC 33 bit counter. BIDIRECTIONAL - Default: INPUT
Bidirectional digital-audio frame clock that is an output in master mode and an input in slave
mode. LRCLKN1 typically is run at the sampling frequency. In slave mode, LRCLKN1 operates
asynchronously from all other CS493XX clocks. In master mode, LRCLKN1 is derived from the
CS493XX internal clock generator. In either master or slave mode, the polarity of LRCLKN1 for
a particular subframe can be programmed by the DSP.
BIDIRECTIONAL - Default: INPUT
Digital-audio data input that can accept from one to six channels of compressed or PCM data.
SDATAN1 can be sampled with either edge of SCLKN1, depending on how SCLKN1 has been
configured. INPUT
Bidirectional digital-audio bit clock that is an output in master mode and an input in slave
mode. In slave mode, SCLKN2 operates asynchronously from all other CS493XX clocks. In
master mode, SCLKN2 is derived from the CS493XX internal clock generator. In either master
or slave mode, the active edge of SCLKN2 can be programmed by the DSP. If the CDI is
configured for bursty delivery, CMPCLK is an input used to sample CMPDAT. BIDIRECTIONAL
