Signal Name:
Signal Description:
Signal Type:
A dual function output that is controlled by the CCR3.5 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 5 msec.
Signal Name:
Signal Description:
Signal Type:
This pin will toggle high for one RCLKA or RCLKB clock cycle for each bipolar Violation (BPV) detected by the
framer.
Signal Name:
Signal Description:
Signal Type:
Sampled on the falling edge of RCLKIA and either rising or falling edge of RCLKIB for data to be clocked
through the receive side framer. RPOSIA
RPOSIA be internally connected to RPOSLO via the CCR4A.2 control bit.
Signal Name:
Signal Description:
Signal Type:
Sampled on the falling edge of RCLKI for data to be clocked through the receive side framer. RPOSIA/B and
RNEGIA/B can be tied together for a NRZ interface. RNEGIA be internally connected to RNEGLO via the
CCR4A.2 control bit.
Signal Name:
Signal Description:
Signal Type:
Signal used to clock data through the receive side framers. RCLKIA can be internally connected to RCLKLO via
the CCR4A.2 control bit.
User Port Pins
Signal Name:
Signal Description:
Signal Type:
These output port pins can be set low or high via the CCR7B.0 to CCR7B.3 control bits. The pins are forced low
on power-up.
