Description

The 831742I 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 four differential, selectable clock/data inputs. The

selected input signal is distributed to two low-skew differential HCSL

outputs. Each input pair accepts HCSL, LVDS and LVPECL levels.

The 831742I is characterized to operate from a 3.3V power supply.

Guaranteed input, output-to-output and part-to-part skew

characteristics make the 831742I ideal for those clock and data

distribution applications demanding well-defined performance and

repeatability. The 831742I supports the clock multiplexing and

distribution of PCI Express (2.5Gb/s), Gen2 (5Gb/s), Gen3 (8Gb/s)

and Gen4 (16Gb/s) clock signals
