Description
The 831724I is a high-performance, differential HCSL clock/data multiplexer and fanout buffer. The device is designed for the multiplexing and fanout of high-frequency clock and data signals. The device has two differential, selectable clock/data inputs. The selected input signal is distributed to four low-skew differential HCSL outputs. Each input pair accepts HCSL, LVDS, LVPECL and SSTL levels. The 831724I is characterized to operate from a 3.3V power supply. Guaranteed input, output-to-output and part-to-part skew characteristics make the 831724I ideal for those clock and data distribution applications demanding well-defined performance and repeatability. The 831724I supports the clock multiplexing and distribution of PCI Express (2.5 Gb/s) and Gen 2 (5 Gb/s) clock signals. The device is a member of the family of High Performance Clock Solutions from IDT.
