Product details

148.5 MHz LVPECL MEMS oscillator — active production

The DSC1122CI2-148.5000T is a 148.5 MHz MEMS-based XO with LVPECL output, part of Microchip's DSC1122 family. It delivers a clean differential clock for high-speed data converters, FPGAs, and SerDes interfaces where LVPECL is the required signaling standard.

Supply rails and temperature fit

Runs from 2.25V to 3.6V, covering both 2.5V and 3.3V logic rails without a separate regulator.

6-SMD no-lead package, 3.20mm x 2.50mm footprint, 0.90mm seated height.

Frequently asked questions

Where can I buy DSC1122CI2-148.5000T?

Sourcing buyers need to quickly find a distributor with stock to place an order.

What is the frequency of DSC1122CI2-148.5000T?
