SIT8209AI-21-18E-157.286400

This SiTime SIT8209AI-21-18E-157.286400 is a MEMS-based oscillator delivering a nominal frequency of 157.2864 MHz. It supports both LVCMOS and LVTTL output types, making it compatible with a wide range of digital logic families. The device operates from a 1.8V power supply with a typical current consumption of 33 mA. Frequency stability is specified at ±20 ppm, ensuring reliable timing accuracy.

The MEMS resonator technology used in this oscillator provides enhanced resistance to shock and vibration compared to traditional quartz-based oscillators, making it suitable for demanding environments. As a standard oscillator (XO), it generates a clean clock signal without requiring external frequency adjustment components.

This component is commonly used in networking, telecommunications, industrial control, and consumer electronics applications where a stable and precise clock source is needed. The absence of package or temperature range data suggests this variant is intended for standard operating conditions; refer to the manufacturer's documentation for additional environmental ratings.
