uPower Oscillator

SiTime’s µPower MEMS oscillators are designed specifically for wearable, IoT, and mobile applications, where space and power are critical. They consume up to 90% lower power and are up to 80% smaller than quartz oscillators. Plus, they are available in the low frequencies that quartz cannot support.

1 Hz to 462.5 kHz Oscillators

The SiT1534 and SiT1569 are the first µPower oscillators capable of a frequency range between 1 Hz and 462.5 kHz in a 1.2 mm2 footprint. In the chip-scale package (CSP), these products reduce a timing device’s footprint by as much as 85% compared to existing 2.0 x 1.2 mm SMD quartz packages. Unlike XTALs, the SiT1534 oscillator output enables greater component placement flexibility and eliminates external load capacitors, thus saving additional component count and board space.

  • Factory programmable from 1 Hz to 462.5 kHz

  • Oscillator output drives multiple loads and eliminates XTALs

  • <±10 ppm frequency tolerance

  • Ultra-low power: <1 µA

  • Smallest footprint available in 1.2 mm2 (1.5 x 0.8 mm) CSP

1 Hz to 2 MHz Oscillators/TCXO

SiTime's SiT1576 & SiT1579 are ultra-small, µPower, low-frequency reference sources that provide new architectural options in wearable, mobile, and IoT applications, where space and power are critical.

  • World's smallest footprint: 1.2 mm2 (1.5 x 0.8 mm) CSP

  • Oscillator output drives multiple loads and eliminates XTALs

  • Ultra-low power: 2.5 to 5.5 μA at 100 kHz

  • ±5 ppm all-inclusive frequency stability (SiT1576) Super-TCXO for improved local timekeeping and system power

  • ±50 ppm all-inclusive frequency stability (SiT1579) oscillator

1 to 26 MHz Oscillators

SiTime’s µPower MEMS oscillators are designed specifically for wearable, IoT, and mobile applications, where space and power are critical. They consume up to 90% lower power and are up to 80% smaller than quartz oscillators. Plus, they are available in the low frequencies that quartz cannot support.
