Output 1 and Output 4 are both 148.25 MHz; Output 2 provides 12 MHz and 24 MHz; Output 3 provides 25 MHz and 100 MHz. Supply voltage range is 2.25 V to 3.6 V, covering 2.5 V and 3.3 V logic rails without an external regulator. ## Frequency plan and output interface Outputs are available in LVCMOS or LVDS format — the 148.25 MHz main clocks are typically routed as LVDS for better signal integrity over longer board traces, while the lower-frequency 12/24 MHz and 25/100 MHz outputs can be LVCMOS for direct connection to FPGA configuration banks or MCU clock inputs. For a 148.25 MHz carrier, ±50 ppm translates to a maximum frequency error of about 7.4 kHz — well within the capture range of most Ethernet PHYs and SerDes reference clocks. The 0.90 mm height keeps it under most mezzanine board clearance limits. Sourced through independent distribution; confirmed availability and current pricing at RFQ.","metaTitle":"DSC400-3111Q0088KI1T Microchip MEMS XO Quad-Output","metaDescription":"Active-production quad-output MEMS oscillator from Microchip.
