Product details

Four-output MEMS XO with LVPECL – what it replaces

The DSC400-2222Q0047KE1 is a MEMS-based XO (Standard) that delivers four independent clock outputs from a single 20-VFQFN package — two at 3.8 MHz and two at 4 MHz, all in LVPECL format. The wide supply range of 2.25V to 3.6V means it runs directly off a 2.5V or 3.3V rail without an external LDO — the LVPECL output swing scales with VDD, so the termination resistors stay the same across both voltages.

Enable/Disable and temperature grade – deployment decisions

It fits indoor equipment, office peripherals, and consumer networking gear, but not an outdoor base station or an engine-bay controller where ambient exceeds 70°C.

No franchised stock is claimed here — each quote is built from the multi-source independent supply base.

Frequently asked questions

What are the exact output frequencies of the DSC400-2222Q0047KE1?

Output 1: 3.8 MHz, Output 2: 4 MHz, Output 3: 4 MHz, Output 4: 3.8 MHz. All four outputs are LVPECL differential signals.

Is the DSC400-2222Q0047KE1 compatible with a 3.3V supply?

Yes. The supply voltage range is 2.25V to 3.6V, so both 3.3V and 2.5V rails are supported directly. The LVPECL output swing tracks VDD, so termination resistors calculated for 3.3V also work at 2.5V.

Does the DSC400-2222Q0047KE1 have an enable/disable pin?

Yes, the function is listed as Enable/Disable. Pulling the pin low disables the outputs, allowing the oscillator to be gated for power savings in idle system states.

Can the DSC400-2222Q0047KE1 replace a standard quartz oscillator?

It can replace a quartz XO in the same package footprint (20-VFQFN) and supply voltage range, provided the system clock tree accepts LVPECL differential inputs and the four output frequencies match the BOM requirements. The MEMS resonator offers better shock and vibration immunity than quartz.
