Product details

MEMS oscillator replaces quartz without a board spin

The DSC1123CI5-034.0000 is a MEMS-based XO (Standard) that outputs 34 MHz LVDS from a 2.25V to 3.63V supply, drawing 32 mA max. The MEMS resonator eliminates quartz startup issues and offers better shock and vibration tolerance — a direct drop-in for standard quartz oscillators in the same 6-SMD footprint.

LVDS output and ±10 ppm stability for differential clock trees

LVDS output delivers a differential pair with low swing, reducing EMI and supporting longer traces on the PCB — typical for FPGA reference clocks, Gigabit Ethernet PHYs, and SerDes transceivers.

Microchip lists the DSC1123CI5-034.0000 as Active.

Frequently asked questions

Is the DSC1123CI5-034.0000 a direct replacement for a standard quartz oscillator?

Yes — the DSC1123CI5-034.0000 uses a MEMS resonator in the same 6-SMD, no-lead footprint as standard quartz XOs. Pin-compatible with the same enable/disable function. The MEMS version offers better jitter, shock resistance, and startup reliability at cold temperatures.
