Product details

MEMS oscillator with dual fixed LVCMOS outputs

The DSC400-0101Q0083KI2 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 package with an exposed pad for thermal relief.

Supply flexibility and output control

Operating from a 2.25V to 3.6V supply rail, this oscillator can be powered directly from a 2.5V or 3.3V logic rail without an intermediate LDO — useful when board space is tight and the voltage budget is already allocated.

Housed in a 20-VFQFN with exposed pad, the 5.00mm x 3.20mm footprint and 0.90mm height fit well in dense mixed-signal boards.

Frequently asked questions

Where can I buy DSC400-0101Q0083KI2?

This part is available through independent distribution. Submit an RFQ with your target quantity and target price; we confirm availability and current pricing at quote time. No stock-holding claim — every order is sourced per request.

What is the frequency stability of DSC400-0101Q0083KI2?

Rated at ±25 ppm over the full -40 to 85°C operating temperature range. This stability is sufficient for most Ethernet, PCIe, and USB reference clocks without external trimming.
