Three-output MEMS clock in a 5×3.2 mm QFN
The DSC400-0333Q0032KE1T is a MEMS-based XO (Standard) oscillator from Microchip's DSC400 series, delivering three independent LVDS clock outputs at 24.576 MHz, 24 MHz, and 25 MHz from a single 20-VFQFN package measuring 5.00 mm × 3.20 mm.
Runs on a 2.25 V to 3.6 V supply, so it sits comfortably on a 2.5 V or 3.3 V rail without an extra LDO.
The ±50 ppm frequency stability across temperature and supply sets the reference accuracy for downstream PLLs and data converters — a 24.576 MHz clock with ±50 ppm drifts no more than about 1.2 kHz worst-case, which is tight enough for a 1000BASE-T Ethernet PHY or an audio codec with a 12.288 MHz MCLK.
