Product details

153.6 MHz and 176.875 MHz dual-output LVPECL oscillator

The DSC400-0202Q0109KI1T is a MEMS-based XO (standard) from Microchip's DSC400 series, delivering two independent LVPECL outputs at 153.6 MHz and 176.875 MHz from a single 20-VFQFN package with an exposed pad for thermal management.

Supply range and enable/disable function

Supply voltage spans 2.25 V to 3.6 V, covering both 2.5 V and 3.3 V rails without an external regulator — the enable/disable pin lets the system gate the clock outputs for power savings or test modes.

Frequently asked questions

What are the exact output frequencies of the DSC400-0202Q0109KI1T?

Output 1 is 153.6 MHz and Output 2 is 176.875 MHz, both LVPECL, from a single MEMS resonator.

Is the DSC400-0202Q0109KI1T compatible with a 3.3 V supply?

Yes — the supply voltage range is 2.25 V to 3.6 V, so both 2.5 V and 3.3 V rails are within spec without an external LDO.
