2. Why did SiTime update the product revision to B?
SiTime enabled a programmable option for a very large customer to accommodate their specific
system level requirement. Consequently SiTime is rolling out revision B to all of our customers
in order to maximize our supply chain and inventory management efficiency.
3. What kind of changes has SiTime made on the rev B?
An additional programmable option is enabled in rev B, but spec-wise, rev B is the same as rev
A, except the IDD max value for 3.3V is slightly higher in the new rev.
4. What is the difference between A and B?
Max current consumption is increased by a small account (0.1 to 0.2 mA) in some cases.
5. What is the benefit of using rev B?
The main benefit over time is better lead time as SiTime will have more rev B inventory in the
channel and at tour factory as our large customers have been or are transitioning over to rev B.
6. Will Rev A still be available?
Yes, there will be absolutely no change for our customers who are using rev A in their existing
designs. We will continue to ship in volume to support these designs.
