Each output can be configured as LVCMOS or LVDS, giving the designer flexibility to drive both single-ended and differential clock domains from one device. The Enable/Disable function allows unused outputs to be gated off for power savings during idle modes. Frequency stability is ±25 ppm across the full temperature range, which keeps the clock edge jitter within the timing budget for 148.5 MHz video links and 156.25 MHz Ethernet reference clocks. ## Package, supply voltage, and PCB layout notes Housed in a 20-VFQFN with exposed pad (5.00 mm x 3.20 mm, 0.90 mm height), the device requires a thermal via array under the pad for proper heat dissipation and electrical grounding. The supply voltage range of 2.25 V to 3.6 V covers common 2.5 V and 3.3 V rails without an external regulator. ## Active production, no last-time-buy concern The product status is Active.","metaTitle":"DSC400-3133Q0100KI2 MEMS XO – Quad Output, LVCMOS/LVDS","metaDescription":"Microchip DSC400-3133Q0100KI2 XO (Standard) with MEMS resonator.
