The SiT1618 is a high-temperature oscillator available in 33 standard frequencies (from 7.3728 MHz to 48 MHz) and two temperature ranges (industrial and automotive). It comes a small 2.0 x 1.6 mm package (4 other packages available), and offers ±20 ppm frequency stability, 3.6 mA low power consumption, and proven shock and vibration resistance. This MEMS-based oscillator can replace quartz crystals (XTAL) without design changes due to its quartz footprint compatibility.
