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.
