SiTime offers a full portfolio of MEMS kHz oscillators and TCXOs. The unique combination of an ultra-small footprint, µPower operation, and accuracy makes the devices an ideal fit for clocking space-sensitive, battery-driven products. With programmable drive strength, these devices can drive multiple loads, such as the BLE sleep clock, RTC, audio, and other connectivity SOCs.
32 kHz Oscillators
SiTime MEMS 32 kHz solutions are ideal for replacing traditional quartz crystal resonators in wearable and mobile applications, where space and power are critical.
- Small footprint at 1.2 mm2 (1.5 x 0.8 mm) in a chip-scale package (CSP)
- Ultra-low power, as low as <1 μA
- NanoDrive™ programmable output swing minimizes power compared to LVCMOS output
- 1.2 V operation-optimized for regulated supply applications, such as coin-cell or super-cap battery backup
- All-inclusive frequency stability, as low as ±50 ppm over temperature

32 kHz TCXOs
The SiTime 32 kHz TCXO lineup is the first to offer ±3 ppm stability in a 1.2 mm2 chip-scale package. The typical core supply current is as low as 1 μA. These 32 kHz TCXOs are factory-calibrated over multiple temperature points to guarantee extremely tight, all-inclusive frequency stability.
- The SiT1552 TCXO offers supply current as low as 0.99 μA, plus NanoDrive™ programmable output to further minimize power consumption
- The SiT1566, SiT1567, and SiT1580 TCXOs offer low integrated RMS phase jitter at 2.5 ns, 2.0 ns, and 1.8 ns respectfully
- The SiT1580 uses the latest generation of EpiSeal® technology which hermetically seals the resonator, making it impervious to all small-molecule gases and immune to external atmospheric elements
