Product details

125 MHz LVDS MEMS oscillator with AEC-Q100 grade

The DSC1123AI5-125.0000T: The Enable/Disable function lets the output tri-state, dropping supply current from 32 mA max to 22 mA max — useful for shared clock trees or power-save modes.

This part carries an Active product status per Microchip. The MEMS resonator construction avoids the quartz supply constraints that occasionally hit crystal-based XOs — the base resonator is MEMS, not a quartz blank.

Package and board-fit note

Housed in a 6-SMD, No Lead Exposed Pad package measuring 7.00 mm × 5.00 mm with a seated height of 0.90 mm. The exposed pad provides a thermal path to the PCB ground plane, though the 32 mA max current draw keeps self-heating low. Supplied on Tape & Reel, which is the standard format for automated pick-and-place assembly.

Frequently asked questions

Is the DSC1123AI5-125.0000T AEC-Q100 qualified?

Yes, it carries an AEC-Q100 rating, meaning it has passed automotive-grade qualification tests including temperature cycling, ESD, and latch-up. This makes it suitable for under-hood and cabin electronics where reliability over temperature extremes is required.

What output type does the DSC1123AI5-125.0000T have?

The output is LVDS (Low-Voltage Differential Signaling). LVDS provides low jitter and good noise immunity for high-speed clock distribution to FPGAs, SerDes, or Ethernet PHYs over short PCB traces.

Where can I find the datasheet for the DSC1123AI5-125.0000T?

The datasheet is available from Microchip's website under the base product number DSC1123. It covers the full family specifications, including jitter, phase noise, and termination recommendations for the LVDS output.
