Product details

MEMS oscillator with dual LVPECL outputs

The DSC400-0202Q0109KE1 is a MEMS-based XO (Standard) from Microchip's DSC400 series, delivering two independent LVPECL output frequencies: 153.6 MHz and 176.875 MHz. It operates from a 2.25 V to 3.6 V supply rail, so it can share a 2.5 V or 3.3 V plane without a dedicated regulator.

Housed in a 20-VFQFN with an exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the thermal pad should be soldered to a ground plane for heat sinking and mechanical stability.

Listed as Active, the DSC400-0202Q0109KE1 is in production and suitable for new designs. No end-of-life notice or successor is recorded.

Frequently asked questions

Can the DSC400-0202Q0109KE1 replace a standard quartz oscillator?

It is a MEMS-based oscillator, not a quartz crystal. It provides a complete clock output (LVPECL) with integrated MEMS resonator, so it can replace a quartz oscillator module with the same output type and frequency, but not a bare quartz crystal.
