DIAGNOSTIC FEATURES:
8.1
PRBS Generator and Detector:
The XRT75L04D contains an on-chip Pseudo Random Binary Sequence (PRBS) generator and detector for
diagnostic purpose. This feature is only available in Host mode. With the PRBSEN_n bit = “1”, the transmitter

JA0_n
This bit along with JA1_n bit configures the Jitter
Attenuator as shown in the table below.
0
D1
JATx/Rx_n Setting this bit selects the Jitter Attenuator in the
Transmit Path. A “0” selects in the Receive Path.
0
D2
JA1_n
This bit along with the JA0_n configures the Jitter
Attenuator as shown in the table.
0
D3
PNTRST_n Setting this bit resets the Read and Write pointers of
the jitter attenuator FIFO.
0
D4
DFLCK_n
Set this bit to “1” to disable fast locking of the PLL.
This helps to reduce the time for the PLL to lock to
incoming frequeny when Jitter Attenuator switches
to narrow band.
