Programmable SPXO SG-8200 series, SG-8201 series
- From standards to high accuracy, low jitter, for wide range of applications -
Overview
The SG-8200 and SG-8201series utilize Epson new low noise fractional-N PLL technology, where the stability has been improved by to 2x and phase jitter has been reduced 1/25th versus the previous generation of Epson programable crystal oscillator. It is ideal for variety of consumer and industrial applications, which requires small form factor and/or operation in harsh environment with wide operating temperature range up to +125°C. This programmable SPXO can be used in small lots and quick turn-around time for any frequency in the range of 1.2 MHz to 170 MHz, contributing to automotive applications from development to mass production.
