Product details

100 MHz LVPECL MEMS XO — industrial temperature, active production

Supply range and output drive — what the 2.25–3.6 V rail means for the board

6-SMD no-lead package — footprint and layout fit

Housed in a 6-SMD no-lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm max. The no-lead (QFN-style) footprint provides a low-inductance ground connection under the device, which is important for maintaining signal integrity on the 100 MHz LVPECL edges. Surface-mount assembly follows standard reflow profiles for QFN packages; no special baking is required unless the moisture-sensitive level demands it.

Microchip lists the DSC1122BI2-100.0000 as Active. No last-time-buy window to track — the BOM line can be treated as a standard active component.

Frequently asked questions

Is DSC1122BI2-100.0000 a drop-in replacement for a quartz crystal oscillator?

The DSC1122BI2-100.0000 is a MEMS-based XO, not a quartz crystal. It is a drop-in replacement for a standard 100 MHz LVPECL quartz oscillator in the same 6-SMD no-lead footprint, with the advantage of better shock and vibration tolerance. No board spin is required if the original oscillator was a 5.0 x 3.2 mm LVPECL XO.
