MEMS XO with dual-frequency output
The DSC400-0101Q0115KI2 is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two independent LVCMOS clock outputs — 12 MHz and 3.072 MHz — from a single 20-VFQFN package with exposed pad.
Runs on a 2.25 V to 3.6 V supply, so it works on either a 2.5 V or 3.3 V rail without a separate LDO — one less part to qualify.
Housed in a 20-VFQFN with exposed pad, 5.00 mm x 3.20 mm body, 0.90 mm height. The 0.50 mm pitch QFN demands a solder paste stencil aperture that matches the pad size on the datasheet footprint — too much paste and the part floats; too little and the corner pins open.
