Low Frequency

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
