HCSL (High-Speed Current Steering Logic) is the standard clock format for PCIe reference clocks, making this oscillator a direct fit for PCIe Gen1/2/3 clock trees where multiple frequencies are needed from a single device. ## Supply range and stability for commercial systems Operating from 2.25 V to 3.6 V, the oscillator covers 2.5 V and 3.3 V rails common in FPGA and ASIC clock domains without an external regulator. ## Active production, available to order Supplied in tape-and-reel (TR) packaging, the 20-VFQFN exposed-pad package measures 5.00 mm x 3.20 mm with a 0.90 mm height, suitable for automated assembly on standard SMT lines.","metaTitle":"DSC400-4444Q0015KE1T MEMS XO – 25/50/125/150 MHz HCSL Quad","metaDescription":"Microchip DSC400-4444Q0015KE1T XO (Standard) MEMS oscillator.
