MEMS quad-output clock in a 5×3.2 mm package
The DSC400-4334Q0022KI1 is a MEMS-based XO (Standard) from Microchip Technology's DSC400 series, delivering four independent clock outputs: two at 125 MHz and two at 100 MHz, selectable between HCSL and LVDS signalling. Housed in a 20-VFQFN exposed-pad package measuring 5.00 mm × 3.20 mm with a 0.90 mm profile, it fits tight board layouts where a single device replaces multiple oscillators.
Operating from 2.25 V to 3.6 V, it covers common supply rails without an extra regulator — useful when the same BOM serves multiple voltage domains. Rated for -40 °C to 85 °C with ±50 ppm frequency stability, this oscillator suits industrial environments like outdoor telecom cabinets, factory-floor controllers, and engine-bay electronics where temperature swings are routine.
