Supply voltage spans 2.25 V to 3.63 V, covering both 2.5 V and 3.3 V rails without an intermediate regulator. At 125 MHz LVDS, the 32 mA ceiling is the number to budget in a multi-oscillator design — four of these on a board add 128 mA to the 3.3 V rail, which is within the margin of a typical 500 mA LDO but worth checking against the regulator's rated output. ## Temperature range and stability That stability spec holds the output frequency within 50 ppm of 125 MHz across the full temperature band — tight enough for a 1 GbE reference clock (±100 ppm is typical for the PHY) without needing a TCXO. 6-SMD, no-lead package, 3.20 mm × 2.50 mm body, seated height 0.90 mm max. The 0.126\" × 0.098\" footprint is a standard 6-pad XO layout — no via-in-pad required, and it fits the same land pattern as many 3.2×2.5 mm LVDS oscillators from other vendors. Product status is Active — Microchip continues to manufacture and support this order code.","metaTitle":"DSC1123CE1-125.0000T – 125 MHz LVDS MEMS XO","metaDescription":"Microchip DSC1123CE1-125.0000T, 125 MHz LVDS output, ±50 ppm stability, 2.25-3.63 V supply, 6-SMD 3.2x2.5 mm, active production.
