Register
Type
Default
Value
(HW reset)
D7
RxTSEL
Receive Termination Select
Upon power up, the receiver is in "High" impedance. RxTSEL is
used to switch between the internal termination and "High" imped-
ance.
0 = "High" Impedance
1 = Internal Termination
R/W
0
D6
TxTSEL
Transmit Termination Select
Upon power up, the transmitter is in "High" impedance. TxTSEL is
used to switch between the internal termination and "High" imped-
ance.
0 = "High" Impedance
1 = Internal Termination
R/W
0
D5
D4
TERSEL1
TERSEL0
Receive and Transmit Line Impedance Select
TERSEL[1:0] are used to select the line impedance for T1/J1/E1.
00 = 100
01 = 110
10 = 75
11 = 120
R/W
0
D3
D2
JASEL1
JASEL0
Jitter Attenuator Select
JASEL[1:0] are used to enable the jitter attenuator in the receive or
transmit path. By default, the jitter attenuator is disabled.
00 = Disabled
01 = Receive Path
10 = Transmit Path
11 = Receive Path
R/W
0
D1
JABW
Jitter Bandwidth (E1 Mode Only, T1 is permanently set to 3Hz)
The jitter bandwidth is a global setting that is applied to both the
receiver and transmitter jitter attenuator.
0 = 10Hz
1 = 1.5Hz
R/W
0
D0
FIFOS
FIFO Depth Select
The FIFO depth select is used to configure the part for a 32-bit or
64-bit FIFO (within the jitter attenuator blocks). The delay of the
FIFO is equal to the FIFO depth. This is a global setting that is
applied to both the receiver and transmitter FIFO.
0 = 32-Bit
1 = 64-Bit
R/W
0
