Product details

100 MHz LVPECL — MEMS oscillator for high-speed clock trees

The DSC1122BI1-100.0000 is a MEMS-based XO (Standard) from Microchip's DSC1122 series, delivering a 100 MHz LVPECL output with ±50 ppm frequency stability. Its supply voltage spans 2.25V to 3.6V, making it compatible with common 2.5V and 3.3V logic rails without an external regulator. The Enable/Disable function lets you gate the output for power savings or test modes — the disable current max is 22 mA versus 58 mA when active.

Industrial temperature grade and MEMS reliability

The MEMS resonator is inherently more shock- and vibration-tolerant than quartz — a practical advantage in motor-drive or automotive environments where crystal failures show up as intermittent clock loss.

New designs can commit to this part without an LTB window.

Frequently asked questions

What is the output type of DSC1122BI1-100.0000?

LVPECL (Low-Voltage Positive Emitter-Coupled Logic). This is a differential output standard requiring 50-ohm termination to Vcc-2V — common on high-speed FPGA and SerDes reference clock inputs.
