Product details

Quad-output MEMS oscillator, HCSL, 20-VFQFN

The DSC400-4444Q0023KE1T is a MEMS-based XO (Standard) oscillator delivering four independent HCSL outputs: two at 100MHz and two at 156.25MHz, all within ±50ppm frequency stability. The HCSL (High-Speed Current Steering Logic) output is common in PCIe and networking clocks, requiring no external termination resistors for a 50-Ω transmission line. Housed in a 20-VFQFN exposed pad package (5.00mm x 3.20mm, 0.90mm height), the part operates from a 2.25V to 3.6V supply and includes an Enable/Disable function.
