- 1Hz to 2MHz, ideal for ultra low power MCUs and AFEs
- 2μA power consumption, battery life up to 10 years
- ±5ppm for precise timing and lowest power consumption
- 1.2mm^2 minimum oscillator, reducing footprint by more than 80%
SiTime Corporation, a wholly-owned subsidiary of MegaChips (Tokyo Stock Exchange: 6875), is a leader in timing solutions based on MEMS technology, and has introduced the SiT1569 oscillator and the SiT1576 Super-TCXO with a wider frequency range. These unique timing solutions are available in a microchip-scale package (CSP) that helps button-battery-powered IoT sensors continue to operate for up to 10 years. Thanks to SiTime's revolutionary TempFlatTM MEMS and mixed-signal technology, these products improve timing accuracy and reduce system power consumption. The ultra-reliable, low-jitter SiT1576 and SiT1569 reference clocks are designed to drive microcontrollers (MCUs) and analog front-end (AFE) modules to support a wide range of portable IoT applications such as railway activity sensors in harsh operating conditions, seismic sensing Interface applications and personal medical diagnostic equipment.
SiTime's executive vice president Piyush Sevalia pointed out: "SiTime's unique timing products are dedicated to providing solutions for the most challenging designs. With the rapid development of the Internet of Things, small size, long-lasting battery life, and high-precision timing requirements, Increasingly important, the SiT1569 oscillator and the SiT1576 Super-TCXO provide the optimal size, power and accuracy needed to support new IoT applications."
About SiT1569 oscillator and SiT1576 Super-TCXO
By replacing the optional quartz oscillator with limited frequency or internally generated (MCU) high-power frequencies and a large form factor, MEMS timing solutions provide designers with unprecedented battery life and significantly reduced size, eliminating the need for precision and I/O pin occupancy issues.
The main technical parameters:
- Minimal package CSP-4 reduces space consumption by up to 80% over quartz solutions
* 1.5mm x 0.8mm (1.2 mm^2 area)
* 0.60mm high, more concealed shape
- Supply current * 2.5μA (100kHz, SiT1569)* 5.5μA (100kHz, SiT1576)
- Frequency range (factory programming helps fast delivery) * 1Hz to 2MHz (SiT1576)* 1Hz to 462kHz (SiT1569)
- Full bread capacitive frequency stability, including initial offset and industrial operating temperature (-40 to +85 ° C) range. A more accurate clock improves timing and extends battery life.
* ±5ppm (SiT1576)* ±50ppm (SiT1569)
- Excellent jitter performance* 2.2ns RMS period jitter (100 kHz, SiT1569)* 4.0ns RMS period jitter (100 kHz, SiT1576)
- Increase startup speed by up to 65%* 300ms (maximum)
- Highest reliability and durability; MEMS resonators are 500 to 1000 times smaller than quartz * 30 times better impact and vibration resistance * 1 billion hours MTBF, 30 times better reliability
