SiTime Corporation 32 kHz TCXOs SiT1552AI-JE-DCC-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 footprint, occupying 1.2 mm² of board space. The device operates over industrial temperature ranges from -40°C to +85°C with frequency stability options of ±5 ppm, ±10 ppm, or ±20 ppm over temperature. It consumes less than 1.52 µA at supply voltages between 1.5 V and 3.63 V, and includes internal power supply filtering that eliminates the need for an external bypass capacitor. The SiT1552AI-JE-DCC-32.768 variant features an LVCMOS output with 1.5 V to 3.63 V compliance and 48% to 52% duty cycle. It is RoHS and REACH compliant and meets JESD22-A114 (3000 V HBM) and JESD22-C101 (750 V CDM) ESD standards. The part is not intended for use in mission-critical systems involving human life.
