SL28PCIE26ALCT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SL28PCIe26ALCT is a PCIe clock generator from the EProClock® PCI Express Gen 2 & Gen 3 Generator series. It accepts a 25 MHz crystal or clock input and provides four 100 MHz differential outputs compliant with PCIe Gen 2 and Gen 3 standards. The device operates on a 3.3V supply (3.135V to 3.465V) within an industrial temperature range of -40°C to +85°C. Key electrical parameters include a cycle-to-cycle jitter of less than 250 ps, a long-term accuracy of 250 ppm, and a dynamic supply current of up to 50 mA. It utilizes a 32-pin QFN package.
