This should be tied low for normal operation. INPUT
MCLK — Audio Master Clock
Bidirectional master audio clock. As an output, MCLK provides a low jitter oversampling clock.
MCLK supports all standard oversampling frequencies. BIDIRECTIONAL - Default: INPUT
SCLK0 — Audio Output Bit Clock
Bidirectional digital-audio output bit clock for AUDATA0, AUDATA1, AUDATA2, and AUDATA3.
As an output, SCLK0 can provide 32 Fs, 64 Fs, 128 Fs, 256 Fs, or 512 Fs frequencies and is
synchronous to MCLK. As an input, SCLK0 is independent of MCLK.
BIDIRECTIONAL - Default: INPUT
SCLK1 — Audio Output Bit Clock
Bidirectional digital-audio output bit clock for AUDATA4, AUDATA5, AUDATA6, and AUDATA7.
As an output, SCLK1 can provide 32 Fs, 64 Fs, 128 Fs, 256 Fs, or 512 Fs frequencies and is
synchronous to MCLK. As an input, SCLK1 is independent of MCLK.
BIDIRECTIONAL - Default: INPUT
LRCLK0 — Audio Output Sample Rate Clock
Bidirectional digital-audio output frame clock for AUDATA0, AUDATA1, AUDATA2, and
AUDATA3. As an output, LRCLK0 can provide all standard output sample rates up to 192 kHz
and is synchronous to MCLK. As an input, LRCLK0 is independent of MCLK.
BIDIRECTIONAL - Default: INPUT
LRCLK1 — Audio Output Sample Rate Clock
Bidirectional digital-audio output frame clock for AUDATA4, AUDATA5, AUDATA6, and
AUDATA7. As an output, LRCLK1 can provide all standard output sample rates up to 192 kHz
and is synchronous to MCLK. As an input, LRCLK1 is independent of MCLK.
BIDIRECTIONAL - Default: INPUT
AUDATA0 — Digital Audio Output 0
PCM digital-audio data output. OUTPUT
AUDATA1 — Digital Audio Output 1
PCM digital-audio data output. OUTPUT
AUDATA2 — Digital Audio Output 2
PCM digital-audio data output. OUTPUT
AUDATA3, XMT958A — Digital Audio Output 3, S/PDIF Transmitter
