MEMS TCXO delivers Stable Timing Solution

MEMS Super-TCXOs: SiT5358 Series

December 9, 2020

RFMW announced design and sales support for SiTime’s SiT5358 series of MEMS Super-TCXOs. The SiT5358 series oscillators  deliver ±50 ppb stability performance and can be factory-programmed to any combination of frequency (from 1 to 60 MHz), voltage and pull range. Fully compliant to the GR-1244 Stratum 3 oscillator specifications, SiTime’s unique DualMEMS™ and TurboCompensation™ temperature sensing technology deliver stable timing in the presence of environmental stressors—airflow, temperature perturbation, vibration, shock and electromagnetic interference (EMI). Programmability enables designers to optimize the clock configuration while eliminating the long lead time and customization costs associated with quartz TCXOs where each frequency is custom built. For example, the SIT5358ANCFR-25E0-38.400000 is programed for 38.4 MHz, clipped sinewave output with a 2.5 volt supply. Applications include, synchronous ethernet, small cells, IEEE1588 boundary clocks, optical transport, radar, wireless backhaul and defense and aerospace.
