SiLabs produces up to 12 ‘any-frequency’ clocks from a single input

Silicon Labs has produced a ‘clock tree on a chip’ with up to 12 outputs. Called Si5332, 230fs(rms) general jitter performance is claimed, with specific examples of: 245fs for clocking system PLLs, 196fs for SerDes PLLs, 220fs for PCIe Gen4 (16Gtransfer/s)and 366fs for FPGAs. The chip comes in three versions, with six, eight or 12 ...
