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
