Product details

Dual-frequency MEMS oscillator for multi-clock BOMs

The DSC400-0101Q0082KI1T is a MEMS-based XO (Standard) from Microchip's DSC400 series, providing two independent LVCMOS clock outputs at 22.5792MHz and 24.576MHz from a single 20-VFQFN package with exposed pad. The 2.25V to 3.6V supply range lets it run from a 2.5V or 3.3V rail without an extra regulator, simplifying the power tree on mixed-voltage boards.

Board-fit and reflow considerations

The 5.00mm x 3.20mm footprint and 0.90mm height match the standard DSC400 land pattern — no exotic pad geometry needed.

Frequently asked questions

What is the frequency stability of the DSC400-0101Q0082KI1T?

±50ppm over the -40°C to +85°C operating temperature range. This is the total stability including initial tolerance, temperature drift, and aging — sufficient for most Ethernet, audio, and video clocking applications.

Can the DSC400-0101Q0082KI1T replace a 22.5792MHz crystal oscillator?

Yes, as a direct drop-in replacement for a 22.5792MHz crystal oscillator in a circuit that expects LVCMOS levels and accepts a 2.25V-3.6V supply. The MEMS oscillator eliminates the need for external load capacitors and offers better frequency stability over temperature than a standalone crystal.

Is the DSC400-0101Q0082KI1T RoHS compliant?

RoHS compliance is standard for Microchip's DSC400 series. The 20-VFQFN package is lead-free compatible with standard reflow profiles.
