Re:PCI/Gigabit Ethernet chipsets

Regarding 10/100/1000Tx Phys, make sure you look at Marvell Semiconductor's
offerings.  They have done extremely well.  No one can match their power
dissipation or package footprint (small 128pin TQFP).  They claim excellent
compliance (and have the UNH reports to prove it) to the standard and
exceed it in some respects.  The Marvell part, if memory serves correctly,
is below 2W.  Their technology is .18um.

Broadcom has the 5400 and the newly announced 5401.   The former has to be
close to 7W.  The latter is about 4W.  Be prepared for heatsinks and
possibly fans.  It is a BGA package.

LevelOne/Intel is still struggling to release their LXT1000.  Because of
heat dissipation, there were forced to repackage the PQFP offering to BGA.

I can't comment on OEM PCI Gigabit MACs as we have our own MAC within the
IBM Power Network Processor.

Which chipsets have you looked at so far(both Macs and PHY's)?  I am also
in the
process of evaluating chipsets for a Gigabit product and would be
interested to
know which ones you are looking at.

 Anyone out there work with or have worked with any PCI-Gigabit Ethernet
Chipsets? I need to implement a solution, but am shocked at the prices of
the chipsets I've found. (Which explains why the darn 10/100/1000bT NIC
cards are so outrageously high...) Our product cannot tolerate the prices
on the devices we have found so far.  Any one know who knows the least
expensive sol'n?


 Thanks!
