[SI-LIST] Re: Resistor Network

Patrick,

CTS makes some BGA resistor packs specifically for DDR memory systems
(SSTL). CTS claims that these resistor packs provide excellent high
frequency performance and help PCB routing (I cannot comment on either
claim).  Of course, there is a price premium....  

See:

Hope this helps...

Regards,

-Mark
