Product details

MEMS oscillator with LVPECL output at 75 MHz

The DSC1122BI2-075.0000: The LVPECL output provides the low-jitter, differential signalling needed for high-speed clock distribution in networking, FPGA reference clocks, and data-converter timing — the 58 mA max supply current reflects the driver's edge-rate demand.

Supply voltage range and enable/disable function

Operates from 2.25V to 3.6V, covering 2.5V and 3.3V rails without a separate regulator — the Enable/Disable pin lets the system gate the output, dropping supply current to 22 mA max when disabled.

Frequently asked questions

Is DSC1122BI2-075.0000 a direct replacement for a standard quartz crystal oscillator?

Yes — as an XO (Standard) with a MEMS resonator, it is pin-compatible with many 6-pin SMD quartz oscillators of the same footprint (5.0 mm x 3.2 mm) and output type. The MEMS base offers better shock and vibration tolerance than a quartz crystal, and the ±25 ppm stability covers most Ethernet, FPGA, and processor reference clock requirements. Confirm the supply voltage and output logic (LVPECL) match your BOM before substituting.
