Signal Name:
Signal Description:
Signal Type:
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
Signal Name:
Signal Description:
Signal Type:
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
Signal Name:
Signal Description:
Signal Type:
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:
Signal Description:
Signal Type:
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:
Signal Description:
Signal Type:
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:
Signal Description:
Signal Type:
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:
Signal Description:
Signal Type:
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.
