Dual-frequency MEMS oscillator for precision clock trees
The DSC400-0101Q0082KI2 is a MEMS-based XO (Standard) oscillator from Microchip Technology's DSC400 series, delivering two independent LVCMOS outputs at 22.5792 MHz and 24.576 MHz from a single 20-VFQFN package with an exposed pad for thermal management. The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails common in FPGA and SoC clock trees, and the Enable/Disable pin lets the system power down the oscillator when the clock domain is idle.
Housed in a 20-VFQFN with exposed pad, 5.00 mm x 3.20 mm body, 0.90 mm height — the pad must be soldered to a thermal via array under the package to keep the MEMS die within the -40°C to 85°C operating range under load.
