1.0 Pin Information (Continued)  
Table 1. NRZ CONTROLLER INTERFACE and MANAGEMENT INTERFACE.  
These pins provide the interface signalling between the Media Access Controller and the transceiver. (30 Pins)

Description  
MDIO  
LINK_4  
94  
I/O  
Management Data I/O: When management interface is enabled (strap option,  
COL[2]=1), this Bidirectional signal transfers data on the management interface be-  
tween the controller and the transceiver.  
Link Lost Status Port 4: When “Disable Management Interface” mode is selected,  
(strap option, COL[2]=0), this pin outputs the link lost status for port 4. If link is lost, this  
output is high.  
INT  
LINK_3  
92  
OD  
Interrupt: When “Enable Management Interface” mode is selected (strap option,  
COL[2]=1), this output pin is driven low when an interrupt condition is detected within  
the Quad Transceiver. Aninterrupt can occur when linkstatus changes or during jabber  
condition. This is an open-drain output. And requires an external pull-up resistor.  
Link Lost Status Port 3: When “Disable Management Interface” mode is selected,  
(strap option, COL[2]=0), this pin outputs the link lost statu3. If link is lost, this  
output is high.  
LINK_2  
LINK_1

O, pull-up Link Lost Status Ports 1,2: These pins indicte the link atus foports 1 and 2.  
O, pull-up (During both management interface disable anable mes)  
LINK_1 is also the strap option for RXD levels duriidle . S eble7 on page11. A  
2.7 kΩ pulldown resistor is needed to set RXD_IDLE High. Default is LINK_1=’1’ and  
RXD_IDLE= Low

On Chip Reference: An external resistor connects to ground for an on chip reference.  
The resistor must be a precision (1%) resistor, the value of which should be determined  
by each user to center VOD around 5 Vpp.
