SiT1534 Ultra-Low Power Programmable Oscillators SiTime SiT1534 Series programmable oscillators are capable of a frequency range between 1Hz to 32.768kHz for true pulse-per-second (PPS) operation. Silicon MEMS technology enables a small footprint and chip-scale packaging. The SiT1534 oscillator's output enables greater component placement flexibility and eliminates external load capacitors, saving additional component count and board space. The SiT1534 features NanoDrive™, a factory programmable output that reduces the voltage swing to minimize power. SiTime MEMS oscillators consist of MEMS resonators and a programmable analog circuit.
