These frequencies align with SMPTE video standards and the 148.35 MHz variant used in certain audio/video synchronisation domains — a single oscillator replaces two discrete XOs on the board. ## Supply voltage tolerance and output format Supply range is 2.25 V to 3.6 V — the oscillator runs from a 2.5 V or 3.3 V rail without an external LDO, and the wide tolerance absorbs rail ripple from a switching regulator upstream. LVDS outputs deliver the clock with a typical 350 mV swing into a 100-Ω differential termination; the differential pair keeps common-mode noise out of the clock tree on a mixed-signal board with digital switching noise. ## Package footprint and thermal management The package measures 5.00 mm x 3.20 mm and stands 0.90 mm off the board — the low profile fits behind a mezzanine card or under a metal shield can.","metaTitle":"DSC400-3333Q0089KI1 XO LVDS 148.35/148.5 MHz MEMS Oscillator","metaDescription":"Active Microchip DSC400 XO, dual LVDS outputs at 148.35 & 148.5 MHz, ±50 ppm stability, -40 to 85°C, 20-VFQFN.
