Product Description
Product Overview
The SG-8018 series crystal oscillator offers a frequency range from 0.67 MHz to 170 MHz with a 1 ppm step, supporting supply voltages from 1.62 V to 3.63 V. It features output enable (OE) or standby (ST ) functions and a frequency tolerance of 50 ppm over an operating temperature range of -40 C to +105 C, including frequency aging. Utilizing PLL technology for short lead times, this oscillator is compatible with the "SG-Writer II" field programmer. It is designed for general electronic applications and specifically designated automotive applications.
