Product details

MEMS oscillator with LVPECL output — 47.998 MHz

The DSC1122CE5-047.9980T is a MEMS-based XO (Standard) oscillator from Microchip, delivering a 47.998 MHz output in LVPECL logic levels — a differential, high-speed signal standard that requires proper termination at the receiver (typically 50 Ω to VCC-2V). Supply voltage spans 2.25V to 3.6V, so it runs on a 2.5V or 3.3V rail without a separate regulator — the LVPECL output swing scales with the supply, so the termination network must be calculated for the actual VCC used.

Package and rework — 6-SMD no-lead

Housed in a 6-SMD no-lead package measuring 3.20 mm × 2.50 mm with a seated height of 0.90 mm — a compact footprint that reflows easily with standard solder profiles.

Frequently asked questions

How can I order the DSC1122CE5-047.9980T or request a quote?

This part is Active and available through independent distribution.

What is the output type of the DSC1122CE5-047.9980T?

LVPECL — a differential, DC-coupled output that typically drives 50 Ω terminated to VCC-2V. It is not compatible with single-ended CMOS inputs without a level translator or AC-coupling network.

Can the DSC1122CE5-047.9980T replace a quartz oscillator?

Yes, it is a drop-in replacement for a standard 47.998 MHz quartz XO in the same 6-SMD footprint, provided the receiving logic expects LVPECL levels. The MEMS resonator is more shock-tolerant and does not require a load capacitor on the board.
