SiTime Corporation 32 kHz TCXOs SiT1566AC-JV-20E-32.768

The SiT1566 is a 1.2 mm² ultra-low power 32.768 kHz MEMS TCXO in a 1.5 x 0.8 mm CSP package, designed for battery-powered applications. It offers ±3 ppm or ±5 ppm total frequency stability over temperature, supply voltage, and load variations. The device operates from 1.62 V to 3.63 V with a typical supply current of 4.5 µA and supports operating temperatures of -20°C to +70°C or -40°C to +85°C. Integrated phase jitter is 2.5 nsRMS, and it includes on-chip filtering, eliminating the need for an external bypass capacitor under normal conditions. The output is LVCMOS compatible with a duty cycle of 45% to 55%. It is Pb-free, RoHS and REACH compliant, with a PFAS-free option available.
