DM9102A

Single Chip Fast Ethernet NIC controller

It connects to a 6200 , 1% error tolerance resistor between

this pin and BGRESG pin to provide an accurate current

reference for DM9102A..

101

BGRESG

I For Bandgap circuit

It is used together with the BGRESG pin.

ISOLATE#

I Isolate

This isolate signal is used to isolate the DM9102A from the

system, and it is suitable for LAN on motherboard. When

isolate signal is active low, it disables the DM9102A function

and the DM9102A will not drive any outputs and sample inputs.

In this case, the power consumption is minimum.
