Product details

MEMS clock at 150.75 MHz LVPECL

The DSC1122CI2-150.7500 is a MEMS-based XO (Standard) that outputs a 150.75 MHz LVPECL differential clock — the standard for high-speed SERDES, FPGA transceivers, and 10GbE reference clocks where jitter budget is tight.

Supply range and disable function

Operates from 2.25V to 3.6V supply, covering 2.5V and 3.3V rails common in networking and FPGA designs.

The DSC1122 series remains a current design-in choice for production builds requiring a 150.75 MHz LVPECL source in a 3.2 mm x 2.5 mm 6-SMD footprint.

Housed in a 6-SMD, No Lead package measuring 0.126" x 0.098" (3.20 mm x 2.50 mm) with a seated height of 0.035" (0.90 mm).

Frequently asked questions

Can the DSC1122CI2-150.7500 replace a 150.75 MHz crystal oscillator directly?

No — this is a MEMS-based XO with an LVPECL differential output, not a quartz crystal oscillator. A crystal oscillator typically outputs a single-ended CMOS or sine wave. The LVPECL output requires AC-coupled termination (50 Ω to VCC-2V) and a differential receiver. Check your clock input buffer before substituting.

Is the DSC1122CI2-150.7500 RoHS compliant?

The evidence does not list a RoHS compliance statement, but as a current Microchip product in a 6-SMD no-lead package it is expected to meet RoHS requirements. Confirm with the datasheet or your Microchip FAE for formal certification.
