Signal Name:
Signal Description:
Signal Type:
This digital input is used to pass a NRZ data stream via the Data Source Selection MUX and the jitter attenuator
block to the RPOSLO and RNEGLO output pins. Data input to this pin is sampled on the falling or rising edge of
PCLK.
Signal Name:
Signal Description:
Signal Type:
This digital input is used to pass a 1.544 MHz clock via the Data Source Selection MUX and the jitter attenuator
block to the RCLKLO output pin.
Signal Name:
Signal Description:
Signal Type:
Set high when the line interface (LIU) detects a carrier loss.
Signal Name:
Signal Description:
Signal Type:
Updated on the rising edge of RCLKLO with either bipolar data out of the LIU or NRZ data from the WNRZ or
PNRZ inputs.
Signal Name:
Signal Description:
Signal Type:
Updated on the rising edge of RCLKLO with either bipolar data out of the LIU or NRZ data from the WNRZ or
PNRZ inputs.
Signal Name:
Signal Description:
Signal Type:
Either a buffered recovered clock from the T1 line or the clock provided at the WCLK or PCLK inputs.
Signal Name:
Signal Description:
Signal Type:
This digital input can be used to select between the WNRZ/WCLK (working) or PNRZ/PCLK (protect) data
inputs. For this pin to be active the Data Source MUX must be properly configured via the CCR1A.2, CCR1A.3,
and CCR1A.4 control bits.
