Dual-frequency MEMS XO for clock-tree consolidation
The DSC400-0101Q0083KE2 is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two independent LVCMOS clock outputs at 45.1584 MHz and 49.152 MHz from a single 20-VFQFN package with an exposed thermal pad. The 2.25 V to 3.6 V supply rail means the same oscillator can be fed from a 2.5 V or 3.3 V plane — no extra regulator or level translator on the clock input.
Enable/Disable pin and package footprint
Housed in a 5.00 mm x 3.20 mm, 0.90 mm height 20-VFQFN with exposed pad, this package demands a solid thermal via array under the pad for heat sinking; the 0.50 mm pitch QFN fan-out fits a 4-layer board comfortably.
Microchip lists the DSC400-0101Q0083KE2 as Active.
