Each output can be configured as LVCMOS or LVDS, so the same oscillator drives a video PLL reference (148.5 MHz LVDS) and a system controller clock (25 MHz LVCMOS) without a fanout buffer. The 2.25 V to 3.6 V supply range covers both 2.5 V and 3.3 V rails — no additional regulator is needed if the board already carries one of these voltages, simplifying the power tree. Frequency stability is ±25 ppm, tight enough for 148.5 MHz video clocking where a one-pixel timing error at 1080p60 is roughly 7.4 ns — the oscillator's jitter contribution stays well below that budget. ## Active lifecycle — no end-of-life tracking required The DSC400 series is a current product family; no successor or replacement part has been announced. ## 20-VFQFN package — layout notes","metaTitle":"DSC400-3133Q0100KI2T MEMS XO – Quad Output, LVCMOS/LVDS","metaDescription":"Microchip DSC400-3133Q0100KI2T quad-output MEMS oscillator: 148.35/148.5 MHz, 156.25 MHz, 25 MHz, 197.8/198 MHz.
