Triple-output MEMS oscillator — 100 / 50 / 125 MHz
The DSC400-0414Q0033KE1T is a Microchip DSC400-series XO (Standard) using a MEMS base resonator, delivering three independent clock outputs: 100 MHz, 50 MHz, and 125 MHz. Outputs are configurable as HCSL or LVCMOS, covering the common reference-clock standards for PCIe, Ethernet, and FPGA transceivers from a single device.
Supply range and stability — ±50 ppm across 2.25–3.6 V
Rated frequency stability of ±50 ppm holds across the 2.25 V to 3.6 V supply range, which means the clock jitter budget does not degrade as the rail droops under load — a common issue with quartz oscillators that pull frequency with supply voltage.
Product status is Active. Supplied in Tape & Reel (TR) packaging, 20-VFQFN exposed pad (5.00 mm × 3.20 mm, 0.90 mm height).
