After close, approximately 163 Renesas employees, including the Timing Products Group and key FAEs, will join SiTime. Their expertise strengthens our technology, design, development, and customer support capabilities.
SiTime and Renesas are committed to supporting as smooth a transition as possible. To this end, we will collaborate closely with the Renesas Clocks & Timing Marketing organization that has been responsible for this as they make the transition to SiTime. Most importantly, we will operate with full transparency with our customers and channel partners to have as clear and robust an understanding of the requirements as possible.
While the Renesas Clocks & Timing FAEs will be joining SiTime, there are no Renesas salespeople coming over as part of the acquisition. Accordingly, your channel partner sales contact should remain the same while sales ownership will transition to SiTime.
Customers should initiate questions by working through their normal points of contact. In the vast majority of cases, this should be your account executive or FAE, whether in the channel or at SiTime. Alternatively, you can send your inquiry to SalesClocks@sitime.com.

Channel partners have set up their internal systems to manage the Clocks & Timing Division orders as a separate entity from the Renesas parent company and quotes as well as pricing will be transitioned automatically and transparently to the customer.
Renesas Clocks & Timing Division Marketing has been handling customer and channel partner prioritizations. Upon transition to SiTime, the joint teams will be heavily engaged in this process.

In this fashion, we can make the appropriate tradeoffs between short-term tactical requirements and longer-term strategic engagements.

This is in response to very strong industry demand overall and will be a combination of both front-end capacity with product transitions to alternative TSMC wafer fabs as well as increasing test throughput within assembly & test. SiTime will be working closely with TPD Marketing to align on actions in this regard and customer communication will be provided once there is clarity on timing and magnitude of these improvements.
