Dual-frequency MEMS oscillator for precision clock trees
The DSC400-0103Q0102KI2T is a MEMS-based XO (Standard) from Microchip's DSC400 series that outputs two independent clock frequencies: 148.5 MHz on output 1 and 14.7456 MHz on output 2, selectable as LVCMOS or LVDS. This dual-output architecture replaces two single oscillators, saving board space and reducing BOM count — the 20-VFQFN package with exposed pad measures 5.00 mm x 3.20 mm.
Temperature grade and supply range for industrial environments
The supply voltage spans 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails without needing a separate regulator — one less component to qualify.
Package and layout considerations for the 20-VFQFN
At 0.90 mm seated height, this part fits in mezzanine-card and blade-server form factors where vertical clearance is under 1 mm.
