SiTime has announced that Square is using the SiTime SiT8008 low-power, programmable MEMS oscillator for its Square Terminal and Square Register point-of-sale (POS) products. The SiT8008 is one of SiTime’s most popular devices and is used in over 50 applications across the enterprise, industrial, mobile, and consumer markets.
The stability of the timing subsystem plays a critical role in ensuring the accuracy of POS products. System vendors do have a choice for timing. They can use a SiTime oscillator, which is an external, standalone timing device, or they can use an on-chip oscillator on their microprocessor/SoC. An external oscillator like the SiT8008 will consistently deliver ten to 100 times better clock stability because of superior MEMS and analog technology and SiTime’s systems expertise. Additionally, the programmable architecture of the SiT8008 provides excellent configurability to the user and ensures fast delivery.
