Question About 6678DSP UDIMM CK0, CK1 routing and SODIMM support

Jin HAO

Dear Sir,/Madam

We are designing our new product which is using C6678 DSP

And currently, we have two questions about 6678DSP:

In the DDR3 Design Datasheet: SPRABI1A, about UDIMM Pin Mapping:

page 116 DDRCLKOUTP0/N0 <=> CK1/CK1#
at the same time, page 119 DDRCLKOUTP0/N0 <=> CK0/CK0#.
Is this correct? Or CK1/CK1# should be connected to DDRCLKOUTP1/N1, not CLKOUTP0/N0?

Can 6678DSP support SODIMM?

Thank you

Regards,

1) This is a typo in SPRABI1A. the line on page 116 should state that DDRLKCOUTP1/N1 should be connected to CK1/CK0#.

2) Unbuffered SODIMM modules use the same DDR3 memories as UDIMM modules. Although we haven't connected an SODIMM to the C6678 we have used UDIMM modules. I don't see any reason why SODIMM couldn't be used.
