The DSC1121CI2-014.3181T is a MEMS-based XO (Standard) from Microchip's DSC1121 series, delivering a fixed 14.3181 MHz CMOS output — a common reference frequency for video timing, graphics controllers, and serial data links. It operates from a 2.25V to 3.6V supply rail, drawing 35 mA max in active mode and 22 mA max when disabled via the Enable/Disable function.
6-VDFN package and surface-mount footprint
Housed in a 6-VDFN package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm, this oscillator fits tight PCB layouts where space is at a premium.
