Debounced SLIC Signaling Inputs for Channel 1-8.
SLIC Signaling I/Os for Channel 1-8.
SLIC Signaling Outputs for Channel 1-8.
Transmit PCM Data Output (For MPI)/GCI Data Upstream (For GCI).
In MPI mode, this pin remains high-impedance until a pulse appears on FS input. PCM data
can output from DX1 or DX2 as selected by serial port, following the BCLK.
In GCI mode, GCI data is serially transmitted on this pin for all 8 channels of IDT821068.
Which part of the GCI data will be occupied is determined by CCLK/TS pin.
Transmit PCM Data Output (For MPI).
This pin remains high-impedance until a pulse appears on FS input. PCM data can output
from DX1 or DX2 as selected by serial port.
This pin is not used in GCI mode.
Receive PCM Data Input (For MPI)/GCI Data Downstream (For GCI).
In MPI mode, PCM data is shifted into DR1 or DR2 following the BCLK. PCM data can input
from DR1 and DR2 as selected by serial port.
In GCI mode, GCI data is received serially on this pin for all 8 channels of IDT821068. Which
part of the GCI data will be transmitted is determined by CCLK/TS pin.
