Краткое описание:
Smallest Footprint (1.2mm2 ) CSP 10 ppm Ultra-Low Power 32.768 kHz XTAL Replacement
Дополнительная информация
The SiT1532 is a 32.768 kHz MEMS oscillator designed as an XTAL replacement for low-power timekeeping applications. It operates from 1.2 V to 3.63 V, draws 0.90 µA typical core current at 1.8 V, and supports NanoDrive programmable output swing to reduce power consumption. The device is offered in a 1.5 x 0.8 mm chip-scale package and provides 10 ppm frequency tolerance at 25°C with up to 100 ppm stability over -40°C to +85°C. Its clock output can connect directly to XTAL inputs without external load capacitors, and internal filtering removes the need for an external bypass capacitor under normal operating conditions.
