The DSC1123AL2-125.0000T is a 125 MHz LVDS MEMS oscillator from Microchip's DSC1123 series — a drop-in timing source for high-speed serial interfaces like PCIe, SATA, or Gigabit Ethernet where LVDS signalling keeps jitter low over the clock trace.
Supply range and enable/disable function
Operates from a single 2.25V to 3.63V supply, covering both 2.5V and 3.3V rails without an external regulator — the internal LDO cleans the rail for the MEMS core.
Housed in a 7.00mm x 5.00mm 6-SMD no-lead exposed pad package. Seated height is 0.90 mm max, so it fits under a conformal coating or inside a potted module without clearance issues.
