The SiT1534 is the first programmable oscillator capable of a frequency range between 32.768 kHz down to 1 Hz for true pulse-per-second (PPS) operation. SiTime's silicon MEMS technology enables the smallest footprint and chip-scale packaging (CSP). These ultra-small µPower devices reduce footprint by as much as 85% compared to existing 2.0 x 1.2 mm SMD XTAL packages. Unlike XTALs, the SiT1534 oscillator output enables greater component placement flexibility and eliminates external load capacitors, saving additional component count and board space. And unlike standard oscillators, the SiT1534 features NanoDrive™, a factory-programmable output that reduces the voltage swing to minimize power.
