Signal Name:
Signal Description:
Signal Type:
An extracted 8kHz pulse, one RCLK wide, is output at this pin that identifies frame boundaries.
Signal Name:
Signal Description:
Signal Type:
If the receive-side elastic store is enabled, an extracted pulse, one RSYSCLK wide, is output at this pin
that identifies multiframe boundaries. If the receive-side elastic store is disabled, then this output will
output multiframe boundaries associated with RCLK.
Signal Name:
Signal Description:
Signal Type:
Updated on the rising edge of RCLK with the data out of the receive-side framer.
Signal Name:
Signal Description:
Signal Type:
1.544MHz, 2.048MHz, 4.096MHz, or 8.192MHz clock. Only used when the receive-side elastic store
function is enabled. Should be tied low in applications that do not use the receive-side elastic store. See
Section
Signal Name:
Signal Description:
Signal Type:
Outputs signaling bits in a PCM format. Updated on rising edges of RCLK when the receive-side elastic
store is disabled. Updated on the rising edges of RSYSCLK when the receive-side elastic store is enabled.
Signal Name:
Signal Description:
Signal Type:
A dual function output that is controlled by the TCR2.0 control bit. This pin can be programmed to either
toggle high when the synchronizer is searching for the frame and multiframe or to toggle high if the
TCLK pin has not been toggled for 5ms.
Signal Name:
Signal Description:
Signal Type:
Set high when the line interface detects a carrier loss.
Signal Name:
Signal Description:
Signal Type:
Set high when the signaling data is frozen via either automatic or manual intervention. Used to alert
downstream equipment of the condition.
