LVDS is the right choice for point-to-point high-speed links where common-mode noise rejection matters — think serializer/deserializer reference clocks, FPGA transceiver banks, or automotive Ethernet PHYs. It fits under-hood or cabin-domain designs where a quartz part might drift or fail under vibration. Operates from 2.25 V to 3.63 V, covering the common 2.5 V and 3.3 V logic rails without an extra regulator. Listed as Active by Microchip. Housed in a 6-SMD, No Lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm. The no-lead land pattern is a direct drop-in for standard 5.0×3.2 mm oscillator footprints — no board spin required if you are replacing a quartz XO in the same form factor.","metaTitle":"DSC1123BE5-156.2500 MEMS XO, 156.25 MHz LVDS, AEC-Q100","metaDescription":"Microchip DSC1123BE5-156.2500: 156.25 MHz LVDS XO, ±10 ppm stability, 2.25V–3.63V supply, AEC-Q100, Enable/Disable.

When disabled, maximum supply current drops to 22 mA."},{"question":"How does this MEMS oscillator compare to a standard quartz XO?","answer":"The MEMS resonator offers better shock and vibration immunity than quartz — a practical advantage in automotive and industrial environments where quartz crystals can fracture or shift frequency. The ±10 ppm stability is comparable to a good quartz XO, but the MEMS part typically starts up faster and has no crystal aging drift over the first year."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1123BE5-156.2500","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1123BE5-156.2500 when reusing this data.
