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.","metaTitle":"DSC2311KL2-R0040T MEMS Oscillator – 40 MHz & 20 MHz CMOS","metaDescription":"Microchip DSC2311KL2-R0040T XO (Standard) with dual outputs: 40 MHz and 20 MHz.

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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC2311KL2-R0040T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC2311KL2-R0040T when reusing this data.
