Dual-output MEMS clock in a 2.5×2.0 mm VDFN
The DSC2311KI2-R0057 is a Microchip MEMS-based XO that delivers two independent CMOS clock outputs — 125 MHz on output 1 and 25 MHz on output 2 — from a single 6-VDFN package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm. Operating from a single 2.25 V to 3.6 V supply rail, the part covers the common 2.5 V and 3.3 V logic levels without a separate voltage regulator.
Frequency stability and temperature grade
The industrial temperature range (-40 to +85 °C) means this oscillator is at home on a factory-floor PLC, a base-station outdoor unit, or an engine-bay ECU that sees ambient heat soak — the MEMS die and CMOS driver are rated to these limits, not just the package.
The standard packaging is Tube, so for high-volume reel quantities confirm the tape-and-reel order code variant with Microchip's packaging options.
