Product details

125 MHz LVDS MEMS oscillator with industrial temperature range

The DSC1103AI2-125.0000 is a 125 MHz XO (Standard) with LVDS output, built on a MEMS resonator. Supply voltage spans 2.25V to 3.63V, so the same oscillator can run from a 2.5V or 3.3V rail without an intermediate LDO. The ±25 ppm frequency stability holds the clock edge jitter within the timing budget for a 125 MHz LVDS link.

Standby power-down for intermittent operation

The standby (power-down) function drops the supply current to 95 µA max when the enable pin is pulled low. In a battery-powered sensor node that sleeps between readings, this cuts the oscillator's draw from 32 mA to near-zero, extending the sleep interval without a separate power switch.

lists the DSC1103AI2-125.0000 as Active — in production and available for new designs. Quoted to order against the BOM quantity; availability confirmed at RFQ.

Frequently asked questions

Is DSC1103AI2-125.0000 compatible with a 2.5V supply?

Yes. The supply voltage range is 2.25V to 3.63V, so a 2.5V rail is well within the operating envelope. The LVDS output levels track the supply, so the receiver's common-mode range must be considered at the lower voltage.

What is the standby power-down feature of DSC1103AI2-125.0000?

The standby (power-down) function disables the output and reduces supply current to 95 µA max. The oscillator draws 32 mA max when active. This is useful for battery-operated or duty-cycled systems where the clock can be gated during sleep.
