8T74S208B - LVDS Clock Divider and Fanout Buffer

Datasheet Summary

Description

The 8T74S208B is a high-performance differential LVDS clock divider and fanout buffer.

The device is designed for the frequency division and signal fanout of high-frequency, low phase-noise clocks.

The 8T74S208B is characterized to operate from a 2.5V power supply.

Features

  • One differential input reference clock.
  • Differential pair can accept the following differential input levels: LVDS, LVPECL, CML.
  • Integrated input termination resistors.
  • Eight LVDS outputs.
  • Selectable clock frequency division of ÷1, ÷2, ÷4 and ÷8.
  • Maximum input clock frequency: 1GHz.
  • LVCMOS interface levels for the control inputs.
  • Individual output enabled/ disabled by I2C interface.
  • Output skew: 45ps (maximum).

2.5V Differential LVDS Clock Divider and Fanout Buffer 8T74S208B Datasheet Description The 8T74S208B is a high-performance differential LVDS clock divider and fanout buffer. The device is designed for the frequency division and signal fanout of high-frequency, low phase-noise clocks. The 8T74S208B is characterized to operate from a 2.5V power supply. Guaranteed output-to-output and part-to-part skew characteristics make the 8T74S208B ideal for those clock distribution applications demanding well-defined performance and repeatability. The integrated input termination resistors make interfacing to the reference source easy and reduce passive component count. Each output can be individually enabled or disabled in the high-impedance state controlled by a I2C register.
