Description
Epson’s SG-9101CGA is Programmable Crystal Oscillator with CMOS output for automotive.
While this series offer the same easy programmability of frequencies and other parameters, with AEC-Q100
compliant and a top-end limit of 125 °C for automotive.
SG-9101CGA has spread spectrum function for reducing EMI, and users will be able to select the required spread
spectrum settings
2.5 × 2.0 mm small package will enable electronics manufacturers to save board space.
