DS125DF111: DS125DF111 and DS110DF111 compatibility "Programming Data Rates"

Part Number: DS125DF111
Other Parts Discussed in Thread: DS110DF111,

TI Design Support Team:

Please advise on DS125DF111 and DS110DF111 programming data rates (0x60-0x64).

We have designed and test the DS110DF111 at various data rates for our product, the DS110DF111 is non-stock with 35 week lead-times.  We would like to use the DS125DF111 as a replacement, but we must ensure our software programmed data rates for the DS110DF111 will work using the DS125DF111 between the 9.95328 Gbps and 11.317642 Gbs as well as 1.25 Gbps.

A review of the DS110DF111 and DS125DF111 data sheets show the programming data rates are identical with the exception of the 9.8304 Gbps.
