RXTXM0
RXTXM[1:0]: Receive and transmit path operation mode select
00= single rail with HDB3 coding
01= single rail with AMI coding
10= dual rail interface with CDR enable
11= slicer mode
30
PULS
PULS: This pin is used to select the following functions:
Transmit pulse template
Internal termination impedance (75
/ 120)
PULS
TCLK
Cable impedance (internal matching impedance)
Cable loss
0
2.048 MHz
75
0-24 dB
1
2.048 MHz

PATT1
PATT0
PATT[1:0]: Transmit test pattern select
In hardware control mode, these pins select the transmit pattern
00 = normal
01= All Ones
10= PRBS
11= transmitter power down
15
14
JA1
JA0
JA[1:0]: Jitter attenuation position, bandwidth and the depth of FIFO select
00= JA is disabled
01= JA in receiver, broad bandwidth, FIFO=64 bits
10= JA in receiver, narrow bandwidth, FIFO=128 bits
11= JA in transmitter, narrow bandwidth, FIFO=128 bits
22
MONT
MONT: Receive monitor n gain select
0= 0 dB
1= up to 26 dB
25
24
LP1
LP0
