SiTime Corporation 32 kHz TCXOs SIT1568AC-JE-DCC-32.768

The SiT1568 is a 32.768 kHz TCXO with ±5 ppm all-inclusive frequency stability, designed for battery-powered applications requiring ultra-low power and high accuracy. It features in-system auto-calibration to compensate for board-level stress-induced frequency errors and is packaged in a 1.5 x 0.8 mm CSP with a footprint of 1.2 mm². The device operates from 1.62 V to 1.98 V, consumes 4.5 µA at no load, and supports operating temperatures from -40°C to +85°C for the "I" ordering code. It provides integrated phase jitter of 2.5 ns RMS and does not require an external bypass capacitor. The part is Pb-free, RoHS and REACH compliant, and features an LVCMOS output with 9 ns to 20 ns rise/fall times. No external components are needed for basic operation.
