IDT8T49N524I - Fractional Clock Generator

General Description

The IDT8T49N524I is an eight output programmable any-rate dual clock generator with selectable LVDS or LVPECL outputs.

Both clock generators use Fractional Output Dividers to be able to generate output frequencies that are independent of each other and independent of the input frequency.

Key Features

  • Fourth Generation FemtoClock® NG PLL technology.
  • Eight outputs selectable as LVPECL or LVDS.
  • Input selectable: fundamental mode crystal or clock reference.
  • Supports fundamental mode crystals from 10MHz - 40MHz.
  • CLK, nCLK input pair can accept the following differential input levels: LVPECL, LVDS, HCSL.
  • Input frequencies from 5MHz up to 800MHz.
  • Two independent output frequencies can be generated.
  • Output frequencies independe.

Programmable FemtoClock® NG LVPECL/LVDS Dual 4-Output Fractional Clock Generator IDT8T49N524I DATA SHEET General Description The IDT8T49N524I is an eight output programmable any-rate dual clock generator with selectable LVDS or LVPECL outputs. Both clock generators use Fractional Output Dividers to be able to generate output frequencies that are independent of each other and independent of the input frequency. Output frequencies for both clock generators are generated from a single crystal or reference clock. Clock Generator A supports three different factory-programmed default frequencies that can be selected from using only the FSEL control pins. Alternatively any desired output frequency can be programmed over the I2C serial port.
