Input/
Output
Transmit Synchronization 1 to 16.
A pulse at these pins establishes either
frame or multiframe boundaries for the transmit side. These signals can also be
programmed to output either a frame or multiframe pulse. If these pins are set to
output pulses at frame boundaries, they can also be set to output double-wide
pulses at signaling frames in T1 mode. The operation of these signals is
synchronous with TCLK[1:16] These pins are selected when the transmit elastic
store is disabled.
Transmit System Synchronization In.
These pins are selected when the
transmit-side elastic store is enabled. A pulse at these pins establishes either
frame or multiframe boundaries for the transmit side. Note that if the elastic store
is enabled, frame or multiframe boundary is established for the transmitters.
Should be tied low in applications that do not use the transmit-side elastic store.
The operation of this signal is synchronous with TSYSCLK[1:16].
Transmit System Synchronization Out.
If configured as an output and the
transmit elastic store is enabled, an 8kHz pulse synchronous to BPCLK1 for
TSSYNCIO[1:8] BPCLK2 for TSSYNCIO[9:16] will be generated. This pulse in
combination with BPCLK[1:2] can be used as an IBO master. TSSYNCIOn can
be used as a source to RSYNCn and TSSYNCIOn of another DS26519 or
RSYNC and TSSYNC of other Dallas Semiconductor parts.

Input
Transmit Signaling 1 to 16.
When enabled, this input samples signaling bits for
insertion into outgoing PCM data stream. Sampled on the falling edge of TCLKn
when the transmit-side elastic store is disabled. Sampled on the falling edge of
TSYSCLKn when the transmit-side elastic store is enabled. In IBO mode, the
TSIGn streams can run up to 16.384MHz. See
