Product details

MEMS XO at 171.8181 MHz — LVDS, industrial temp, active production

The part is specified across -40 to 85°C with ±25 ppm frequency stability, covering the industrial temperature band. A design team specifying this for a base station, a motor drive, or a surveillance camera clock tree gets the temperature margin without overspecifying to a TCXO.

Sourcing posture — active, no obsolescence risk

Microchip lists the DSC1103AI2-171.8181 as Active. The supply voltage range spans 2.25 V to 3.63 V, making it compatible with common 2.5 V and 3.3 V logic rails without an external regulator.

Package and footprint — 7×5 mm, 6-SMD with exposed pad

The 6-SMD, No Lead Exposed Pad package measures 7.00 mm × 5.00 mm with a seated height of 0.90 mm.

Frequently asked questions

What is the standby function of the DSC1103AI2-171.8181?

The Standby (Power Down) function disables the output and reduces the supply current to 95 µA max. When the standby pin is asserted, the oscillator stops toggling and the downstream device sees a static LVDS level. De-asserting the pin restarts the output; the MEMS resonator starts faster than a quartz crystal, so the clock is valid within a few microseconds.

Is the DSC1103AI2-171.8181 RoHS compliant?

The evidence does not carry an explicit RoHS compliance statement. Confirm the date code and the manufacturer's RoHS certification at the time of ordering — the 6-SMD package is lead-free compatible, but the compliance status should be verified against the specific lot.
