MODE[1:0]: Operation mode of Control interface select (global control)
00= Hardware interface
01= Serial interface
10= Parallel - non-Multiplexed - Motorola Interface
11= Parallel - non-Multiplexed - Intel Interface
TERMn: Termination interface select (per channel control)
These pins select internal or external impedance matching for channel n (n=1 or 2)
0 = ternary interface with internal impedance matching network.
1 = ternary interface with external impedance matching network in E1 mode; ternary interface with external impedance matching
network for receiver and ternary interface with internal impedance matching network for transmitter in T1/J1 mode. (External imped-
ance matching is not supported by T1/J1 mode transmitter.)
(This applies to ZB die revision only).
RXTXM[1:0]: Receive and transmit path operation mode select (global control)
00= single rail with HDB3/B8ZS coding
01= single rail with AMI coding
10= dual rail interface with CDR enable
11= slicer mode
PULSn[3:0]: These pins are used to select the following functions (per channel control):
•
•
•
EQn: Receive Equalizer on/off control (per channel control)
When the chip is configured by hardware with ternary interface, these pins select Short Haul or Long Haul operation mode for chan-
nel n (n=1 or 2)
0= short haul (10dB)
1= long haul (36dB for T1/J1, 43 dB for E1)
RPDn: Receiver power down control (per channel control)
0= Normal operation
1= receiver power down
