Signal Name:
TLINK
Signal Description:
Transmit Link Data
Signal Type:
Input
If enabled, this pin will be sampled on the falling edge of TCLK for data insertion into any combination
of the Sa bit positions (Sa4 to Sa8). See Section 18 for details. This signal is not bonded out in the
DS21FF44/DS21FT44.
Signal Name:
TSYNC
Signal Description:
Transmit Sync
Signal Type:
Input /Output
A pulse at this pin will establish either frame or multiframe boundaries for the transmit side. This pin can
also be programmed to output either a frame or multiframe pulse. Always synchronous with TCLK.
Signal Name:
TSSYNC
Signal Description:
Transmit System Sync
Signal Type:
Input
Only used when the transmit side elastic store is enabled. A pulse at this pin will establish either frame or
multiframe boundaries for the transmit side. Should be connected low in applications that do not use the
transmit side elastic store. Always synchronous with TSYSCLK.
Signal Name:
TSIG
Signal Description:
Transmit Signaling Input
Signal Type:
Input
When enabled, this input will sample signaling bits for insertion into outgoing PCM E1 data stream.
Sampled on the falling edge of TCLK when the transmit side elastic store is disabled. Sampled on the
falling edge of TSYSCLK when the transmit side elastic store is enabled. This function is available when
FMS = 0. FMS is connected to ground for the DS21FF44/DS21FT44.
Signal Name:
TPOS
Signal Description:
Transmit Positive Data Output
Signal Type:
Output
Updated on the rising edge of TCLK with the bipolar data out of the transmit side formatter. Can be
programmed to source NRZ data by the Output Data Format (TCR1.7) control bit.
Signal Name:
TNEG
Signal Description:
Transmit Negative Data Output
Signal Type:
Output
Updated on the rising edge of TCLK with the bipolar data out of the transmit side formatter.
RECEIVE SIDE PINS
Signal Name:
RLINK
Signal Description:
Receive Link Data
Signal Type:
Output
Updated with full recovered E1 data stream on the rising edge of RCLK. This signal is not bonded out in
the DS21FF44/DS21FT44.
