MODE[1:0]: Operation mode of control interface select
00= Hardware interface
01= Serial interface
10= Parallel – multiplexed – Motorola Interface
11= Parallel – multiplexed – Intel Interface
TERM: Termination interface select
This pin selects internal or external impedance matching for both receiver and transmitter
0= ternary interface with external impedance matching network. External impedance matching is not supported in T1/J1 transmit
1= ternary interface with internal impedance matching network
RXTXM[1:0]: Receive and transmit path operation mode select
00= single rail with HDB3/B8ZS coding
01= single rail with AMI coding
10= dual rail interface with CDR enable
11= slicer mode
PULS[3:0]: These pins are used to select the following functions:
•
•
•
RPD: Receiver power down control
0= Normal operation
1= receiver power down
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
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
