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 Table 9-9.
