Product Overview
The SG-8101 series crystal oscillator offers a wide frequency range from 0.67 MHz to 170 MHz with 1 ppm step programmability. Designed for flexibility, it supports supply voltages from 1.62 V to 3.63 V and features output enable (OE) or standby (ST) functions. Available in various frequency tolerances and operating temperatures, these oscillators are suitable for applications requiring precise timing. The series utilizes PLL technology for short lead times and is compatible with the SG-Writer II programmer for field programmability. Applications include automotive systems like Car Multimedia, Body Electronics, Remote Keyless Entry, and driving safety systems such as Engine Control Units and Air Bags.
