The LVDS differential pair keeps jitter low over board traces longer than a few inches, which a single-ended CMOS clock at this frequency would struggle to maintain without signal degradation. The supply range spans 2.25V to 3.63V — it runs from a 2.5V or 3.3V rail without a separate LDO.","metaTitle":"DSC1123AI5-322.2656 XO 322.2656 MHz LVDS MEMS Oscillator –","metaDescription":"DSC1123AI5-322.2656: XO (Standard) LVDS output, 322.2656 MHz, ±10 ppm stability, -40°C to 85°C, 6-SMD.

Submit an RFQ with your target quantity; we confirm current pricing and lead time at quote. No stock-holding claim is made — availability is confirmed per order."},{"question":"Is DSC1123AI5-322.2656 compatible with a 3.3V supply?","answer":"Yes. The supply voltage range is 2.25V to 3.63V, so a 3.3V rail is within spec. The LVDS output common-mode voltage and swing are referenced to the supply, so the receiver must accept the levels generated at 3.3V."},{"question":"Can a MEMS oscillator like DSC1123AI5-322.2656 replace a quartz crystal oscillator?","answer":"Functionally yes — it provides a fixed-frequency clock output without external load capacitors or a crystal. The MEMS construction offers better shock and vibration tolerance than quartz, and the ±10 ppm stability is comparable to a standard quartz XO. The trade-off is that the frequency is factory-programmed and cannot be pulled (no VCXO function)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123AI5-322.2656","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123AI5-322.2656 when reusing this data.
