831742I

Datasheet

Description

Features

• 4:2 differential clock/data multiplexer with fanout

• Four selectable, differential input pairs

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.

• Each differential input pair can accept the following levels: HCSL,

LVDS and LVPECL

• Two differential HCSL output pairs

• Maximum input/output clock frequency: 700MHz

• Maximum input/output data rate: 1400Mb/s (NRZ)

• LVCMOS interface levels for all control inputs

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), Gen 2 (5Gb/s) and

Gen 3 (8Gb/s) clock signals.

• PCI Express (2.5Gb/s), Gen 2 (5 Gb/s) and Gen 3 (8 Gb/s) clock

jitter compliant

• Input skew: 110ps max

• Part-to-part skew: 225ps max

• Full 3.3V supply voltage

• Available in lead-free (RoHS 6)

• -40°C to 85°C ambient operating temperature
