DS21354/DS21554 3.3V/5V E1 Single-Chip Transceivers
15 of 124
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 13 for details.
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. Via TCR1.1,
the DS21354/DS21554 can be programmed to output either a frame or multiframe pulse at this pin. This
pin can also be configured as an input via TCR1.0. See Section 18 for details.
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 tied low in applications that do not use the
transmit-side elastic store.
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.
Signal Name:
TESO
Signal Description:
Transmit Elastic Store Data Output
Signal Type:
Output
Updated on the rising edge of TCLK with data out of the transmit-side elastic store whether the elastic
store is enabled or not. This pin is normally tied to TDATA.
Signal Name:
TDATA
Signal Description:
Transmit Data
Signal Type:
Input
Sampled on the falling edge of TCLK with data to be clocked through the transmit-side formatter. This
pin is normally tied to TESO.
Signal Name:
TPOSO
Signal Description:
Transmit Positive Data Output
Signal Type:
Output
Updated on the rising edge of TCLKO with the bipolar data out of the transmit-side formatter. Can be
programmed to source NRZ data via the Output Data Format (TCR2.2) control bit. This pin is normally
tied to TPOSI.
