Product details

125 MHz LVDS MEMS oscillator with standby

The DSC1103AE1-125.0000 is a MEMS-based XO (Standard) oscillator delivering a 125 MHz LVDS output with ±50 ppm frequency stability across -20°C to +70°C. It operates from a 2.25V to 3.63V supply, drawing 32 mA max from the rail while active, and drops to 95 µA max in standby (power-down) mode. The standby function disables the output and places the oscillator in a low-power state, making it suitable for intermittent-duty or battery-powered systems where the clock tree can be gated.

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00mm x 5.00mm with a seated height of 0.90mm — a standard 7x5 mm oscillator footprint that matches many quartz XO land patterns.

Frequently asked questions

What is the difference between MEMS and quartz oscillators?

A MEMS oscillator uses a silicon micro-electromechanical resonator instead of a quartz crystal. It is factory-trimmed to frequency, requires no external load capacitors, and offers better resistance to vibration and shock. The trade-off is typically a slightly wider frequency stability specification compared to a high-end quartz TCXO, though the ±50 ppm stability here is adequate for most Ethernet, PCIe, and general-purpose clock applications.
