Re: [Gumstix-users] Gigabit Ethernet and PCI Express

[Gerardo R. <ge...@di...>]

I'd still would like to hear from you guys, but moving forward I've
found two chips that may serve as 1GHz interface to an overo.

SMSC's LAN7500
(http://www.smsc.com/index.php?tid=292&pid=258&cid=&tab=3) and
SiliconLab's CP2200/1
(http://www.silabs.com/products/interface/ethernetcontrollers/Pages/default.aspx)

LAN7500 is a USB to Ethernet (10/100/1000) with existing linux support
(not sure how good) which has been used with an OMAP4460 at least
(http://www.directinsight.co.uk/products/swiftmodule/SwiftModule-omap-4460.html
or
http://atlantis.com.ua/rpstr/catalog/VAR-SOM-OM44_v0.91_datasheet_v1.0.pdf).
This seems a good choice, though going via USB to get Ethernet sounds a
bit counterintuitive (or doesn't?).

CP2200/1 has a parallel interface, with address and data lines. Though
even after reading the datasheet I'm not sure if it can do 100/1000 or
if it's just 10 and "compatible with 100/1000" means it can be plugged
into a high speed network, but just work at 10 Mbps.

	any other candidates? comments?

	thanks!
