Delivering Unmatched Combination of 30x Higher Reliability, 4x Smaller Size, and 4x Lower Power

SiTime Corp. (NASDAQ: SITM), the precision timing company, today announced the SiT5503 Elite X™ Super-TCXO^®, that raises the bar on timing performance in data centers and 5G infrastructure. By 2024, the addressable market for precision timing in Comms-Enterprise is expected to be $1.3 billion. The SiT5503 Elite X Super-TCXO will address $200M of this market by delivering an unmatched combination of features and performance that enable faster, more reliable networks.

“Today’s 5G and edge network applications require precision timing solutions designed to operate reliably in demanding environments,” said Piyush Sevalia, EVP marketing, SiTime. “With the SiTime SiT5503 MEMS Super-TCXO, system designers now have a compelling solution. They can replace large, power-hungry quartz OCXOs with the SiT5503, and meet the operators’ holdover requirements, even in the presence of severe environmental stressors.”

To transfer data at higher speeds and lower latency, networks need a stable and reliable clock that is generated by a timing grandmaster in the core and is transmitted to all nodes in the network. To ensure uptime, downstream edge networks have a redundant, local, stable clock that continues to operate even if the network clock is disrupted. The amount of time that the local clock can operate and maintain the same accuracy as the network clock is called holdover, which, in edge networks, is typically 4 hours. The SiTime SiT5503 Super-TCXO meets this requirement.
