333.33 MHz LVDS clock — what it drives and where it fits
The DSC1123DI1-333.3300T is a 333.33 MHz LVDS oscillator from Microchip's DSC1123 MEMS family. That frequency and output type target SERDES reference clocks, FPGA high-speed fabric clocks, and data-converter sampling clocks where a differential signal keeps noise off the clock trace.
Frequency stability and supply rail
For a 10 GbE reference clock, ±50 ppm is the standard window; the oscillator does not consume margin that belongs to the rest of the link.
Housed in a 6-VDFN package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — a compact footprint that fits dense PCB layouts.
