Driver Failure Monitor Output. When High, indicates a driver short in one of the output drivers.
The LOSx output identifies the specific failing driver in this case.
Receive Negative Data/Bipolar Violation Indication Output–Port 3. All RNEGx/BPVx pins are
identical. In bipolar mode these pins act as active High bipolar non-return-to-zero (NRZ) receive
signal outputs. A High signal on RNEGx corresponds to receipt of a negative pulse on RTIPx/
RRINGx. A High signal on RPOSx corresponds to receipt of a positive pulse on RTIPx/RRINGx.
Both signals are valid on the same edge of RCLKx, as determined by CNTL1 and CNTL2.
In unipolar mode, the LXT334 asserts the BPVx pin High any time it senses an In-Service Line
Code violation.
(In data recovery mode, this pin is active Low.) See RPOS3/RDATA3, pin 50; and Functional
Description.
Receive Positive Data/Receive Data Output–Port 3. A High signal on RPOSx corresponds to
receipt of a positive pulse on RTIPx/RRINGx. This signal is valid on the edge of RCLKx
determined by CNTL1 and CNTL2.
In unipolar mode (selected by pulling TNEGx High for more than 16 TCLKx periods) the LXT334
asserts RDATAx High when a mark has been received and is valid on the falling edge of RCLKx.
RDATAx is an NRZ receive data output.
(In Data Recovery mode, this pin is active Low.) See RNEG3/BPV3, pin 49.
