PIN DESCRIPTION (CONTINUED)  
SERIAL-PORT PINS  
NAME  
PIN TYPE DESCRIPTION  
[SPSL=1] Serial-Port Enable:  
High during read and write operations. Low disables the serial port.  
While SEN is low, SDO remains in high impedance state, and SDI and  
SCK activities are ignored.  
SEN_CMI

CI  
[SPSL=0] Medium Select:  
Low: Fiber (NRZ pass-through) mode  
High: CMI mode  
[SPSL=1] Serial Clock:  
Controls the timing of SDI and SDO.  
[SPSL=0] Receive Monitor Mode Enable:  
SCK_MON  
When high, adds 20dB of flat gain to the incoming signal of both  
channels before equalization.  
NOTE: Channel specific monitor modes can be enabled through the  
serial port. Rx Monitor Mode is only available in CMI mode  
[SPSL=1] Serial Data Input:  
Inputs mode and address information. Also inputs register data during  
a Write operation. Both address and data are input least significant bit  
first.  
SDI_PAR  
SDO_E4  
94  
93  
[SPSL=0] Data Width Select:  
Selects 4 bit parallel transmit modes (input high) or serial transmit  
modes (input low)  
[SPSL=1] Serial Data Output:  
Outputs register information during a Read operation. Data is output  
COZ/  
CI  
least significant bit first  
[SPSL=0] Rate Select:  
Selects E4 operation (input high) or STM1/STS3 operation (input low)  
POWER AND GROUND PINS  
It is recommended that all supply pins be connected to a single power supply plane and all ground pins be  
connected to a single ground plane. See application note for decoupling guidelines.
