R/W
D0
JA0
This bit along with JA1 bit configures the Jitter Attenu-
ator as shown in the table below.
0
D1
JATx/Rx
Writing a “1” to this bit selects the Jitter Attenuator in
the Transmit Path. A “0” selects in the Receive Path.
0
D2
JA1
This bit along with the JA0 configures the Jitter Atten-
uator as shown in the table.
0
D3
PNTRST
Setting this bit to “1” resets the Read and Write point-
ers of the jitter attenuator FIFO.
0
D4
DFLCK
Set this bit to "1" to disable the SONET APS Recov-
ery Time of the PLL. When this bit is "0", the APS
Recovery Time is enabled. This helps to reduce the
time for the PLL to lock to the incoming frequency
when the Jitter Attenuator switches to narrow band.
This is required for SONET to DS-3 Mapping/Demap-
ping De-Synchronization applications.
