14.3182 MHz timing reference for video and USB
The DSC1001CE1-014.3182 is a MEMS-based XO (Standard) from Microchip's DSC1001 series, delivering a 14.3182 MHz CMOS output — the frequency used for NTSC video pixel clocks, USB full-speed host controllers, and legacy graphics subsystems. The ±50 ppm frequency stability keeps the colour burst and serial data timing within spec without external trimming.

Supply tolerance and layout note
The 1.8V to 3.3V supply range covers common logic rails without a dedicated regulator — the same oscillator can run from a 1.8V MCU I/O bank or a 3.3V peripheral bus. The 4-SMD No Lead package (3.20mm x 2.50mm) keeps the footprint compact; a 100 nF decoupling capacitor within 2 mm of the supply pin is recommended to keep the phase-noise floor clean under digital switching noise.
Active production and ordering
The base product number DSC1001 covers other frequencies and stability grades if the design needs a different reference.
