Clock generator
CE915GM modules use the ICS954201 clock synthesizer from Integrated Circuit Systems,
Inc. The ICS954201 is driven by a 14.318MHz crystal, and generates CPU outputs up to
400MHz. This chip fully supports the ppm accuracy required by Serial ATA and PCI Express.
For detailed specifications on the ICS954201 clock synthesizer, refer to the ICS Web site,

.
System memory
CE915GM modules provide one
200-pin SO-DIMM socket to accept DDR2-400/533 64-bit,
non-ECC, non-parity memory modules. 128MB to 1GB memory is supported.
The socket can accept either single or double-sided modules. Visit
www.radisys.com
for a
list of memory tested with this product. In general, compatible memory modules must:
•
Comply with the JEDEC DDR2 specification for 1.8V 200-pin unbuffered DDR2 SDRAM
PC2-3200/PC2-4200/PC2-5300 DDR2 (DDR2-400/533) unbuffered SO-DIMM modules.
•
Support bus speeds of PC2-3200 (400MHz) or PC2-4200 (533MHz).
