µPower Oscillators 1 Hz to 26 MHz

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 oscillator: <1 µA
• Small footprint available in 1.2 mm² (1.5 x 0.8 mm) CSP

With flexible frequencies, these ultra-small, µPower, low-frequency reference sources provide new architectural options in wearable, mobile, and IoT applications, where space and power are critical.

• World's smallest oscillator 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
• The SiT1576 TCXO provides ±5 ppm all-inclusive frequency stability for improved local timekeeping and system power
• The SiT1580 TCXO uses the latest generation of EpiSeal® technology which hermetically seals the resonator, making it impervious to all small-molecule gases and immune to external atmospheric elements

SiTime’s µPower MEMS oscillators are designed for wearable, IoT, and mobile applications, where space and power savings are critical. Our µPower oscillators consume up to 90% less power and up to 80% less space compared to quartz oscillators. Plus, they are available in low frequencies that quartz cannot support.

• Smallest oscillator footprint: 1.2 mm² (1.5 x 0.8 mm) CSP
• Low power: 0.1 mW of active power consumption at 3 MHz
• Oscillator output drives multiple loads and eliminates XTALs
• For digitally controlled µPower oscillators, see SiT3901 DCXO

SiTime automotive MEMS 32-kHz oscillators can also support 17 other frequencies from 1 Hz to 262.144 kHz. With ultra-low power consumption, best-in-class frequency stability, and small size, these devices are ideal when space and power are critical. 

• Small 1.32 mm² (1.2 x 1.1 mm) footprint, up to 75% smaller compared to 2.0 x 1.2 mm SMD crystals (XTAL)
• Ultra-low power at 490 nA
• All-inclusive frequency stability at ±50 ppm, up to 105°C
• LVCMOS output, plus new Reduced Swing technology to further minimize overall system power
• Drives up to 100 pf of load, eliminating multiple 32.768 kHz crystals in a design
