5502 and SDRAM on 150MHz clock - is it possible or I'm just lucky?

Started by alte...@gmail.com August 22, 2007
Hi all!

I use 5502 chip with 300 MHz clock frequency and configured PLLDIV3 so that SYSCLK30 MHz. It is far above allowed 100 MHz (SPRS166J, page 58, 3.10.4.4 External Memory Interface Clock Group) but everything seems to be ok. The chip write and read back MT48LC4M16A2 SDRAM (166 MHz Max Clock Frequency) properly. Have anyone tried to operate 5502 with 150MHz SDRAM clock? Can I rely on this result in serial production?
