Product details

Dual-output MEMS oscillator – 40 MHz and 20 MHz from one package

The DSC2311KL2-R0040T is a MEMS-based XO (Standard) from Microchip's DSC2311 series, delivering two synchronous CMOS clock outputs: 40 MHz on output 1 and 20 MHz on output 2. A single 6-VDFN package replaces two discrete quartz oscillators, saving board area and reducing BOM count for dual-clock applications like Ethernet PHY + SoC or FPGA + memory controller.

Supply voltage and temperature coverage

Runs on any rail from 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic without an external LDO — the same part works across a multi-voltage board. An outdoor base-station or a motor-drive controller that sees 85°C ambient still has 20°C of margin before the upper limit.

Frequently asked questions

Can the DSC2311KL2-R0040T replace a standard quartz oscillator?

Yes, in most cases. The MEMS-based DSC2311KL2-R0040T is pin-compatible with many 6-VDFN quartz oscillators and offers better shock/vibration tolerance. The dual-output (40 MHz + 20 MHz) means it can replace two single-output oscillators if the board layout supports the 6-VDFN footprint. Confirm the supply voltage (2.25–3.6 V) and output type (CMOS) match your design.
