SiTime Corporation 32 kHz TCXOs SiT1552AI-J1-D26-32.768

The SiT1552 is a 32.768 kHz MEMS temperature-compensated crystal oscillator (TCXO) designed for ultra-low power timekeeping applications. It is packaged in a 1.5 x 0.8 mm CSP with a die area of 1.2 mm². The device operates from 1.5 V to 3.63 V with a core current of 0.99 µA at 25°C and 1.8 V, rising to 1.52 µA across the full industrial temperature range of −40°C to +85°C. Frequency stability options are ±5, ±10, and ±20 ppm over temperature, with initial offset included. Output is LVCMOS, with rise/fall times of 100 to 200 ns into 15 pF. Internal filtering eliminates the need for an external Vdd bypass capacitor. The device is Pb-free, RoHS and REACH compliant, with PFAS-free options available.
