Signal Name:
Signal Description:
Signal Type:
A dual function output that is controlled by the CCR1.0 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 5µs.
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 by either automatic or manual intervention. Used to alert downstream
equipment of the condition.
Signal Name:
Signal Description:
Signal Type:
A user-selectable synthesized clock output that is referenced to the clock that is output at the RCLK pin.
Signal Name:
Signal Description:
Signal Type:
Updated on the rising edge of RCLKO with bipolar data out of the line interface. This pin is normally connected to
RPOSI.
Signal Name:
Signal Description:
Signal Type:
Updated on the rising edge of RCLKO with the bipolar data out of the line interface. This pin is normally
connected to RNEGI.
Signal Name:
Signal Description:
Signal Type:
Buffered recovered clock from the network. This pin is normally connected to RCLKI.
Signal Name:
Signal Description:
Signal Type:
Sampled on the falling edge of RCLKI for data to be clocked through the receive-side framer. RPOSI and RNEGI
can be connected together for an NRZ interface. Can be internally connected to RPOSO by connecting the LIUC
pin high.
