SIX CHANNEL E3/DS3/STS-1 LINE INTERFACE UNIT WITH JITTER ATTENUATOR

DIAGNOSTIC FEATURES
5.1
The XRT75L06 contains an on-chip Pseudo Random Binary Sequence (PRBS) generator and detector for
diagnostic purpose. With the PRBSEN_n bit = “1”, the transmitter will send out PRBS of 2
23
-1 in E3 rate or
2
15
-1 in STS-1/DS3 rate. At the same time, the receiver PRBS detector is also enabled. When the correct
PRBS pattern is detected by the receiver, the RNEG/LCV pin will go “Low” to indicate PRBS synchronization
has been achieved. When the PRBS detector is not in sync the PRBSLS bit will be set to “1” and RNEG/LCV
pin will go “High”.
With the PRBS mode enabled, the user can also insert a single bit error by toggling “INSPRBS” bit. This is
done by writing a “1” to INSPRBS bit. The receiver at RNEG/LCV pin will pulse “High” for one RxClk cycle for
every bit error detected. Any subsequent single bit error insertion must be done by first writing a “0” to
INSPRBS bit and followed by a “1”.
Figure 29 shows the status of RNEG/LCV pin when the XRT75L06 is configured in PRBS mode.
