Four clocks from one MEMS resonator
It delivers 25 MHz, 24 MHz, and 33.333333 MHz on three of those outputs, with the fourth available for a custom frequency per the factory configuration. Frequency stability is ±25 ppm across the full –40 to +85°C industrial temperature range, and the supply voltage spans 2.25 V to 3.6 V — one BOM line covers 2.5 V, 3.0 V, or 3.3 V core rails without a change order.
Microchip lists the DSC400-0111Q0087KI2 as Active.
20-VFQFN footprint notes
Housed in a 20-VFQFN with exposed pad, 5.00 mm x 3.20 mm body, 0.90 mm height. The exposed thermal pad needs a solid via-stitched ground plane on the PCB — without it the MEMS die's junction-to-board thermal resistance rises and the frequency drift under load widens beyond the ±25 ppm spec.
