General Description

The DS50EV401 is a low power, programmable equalizer specifically designed to reduce inter-symbol interference (ISI) induced by a variety of interconnect media.

In all modes, the equalizer can operate, error free, with an input eye that is completely closed by interconnect ISI.

The MODE control, allows the user to select between equalization settings for 8.0 Gbps operation or 2.5 Gbps / 5.0 Gbps operation.

Key Features

  • Automatic power management on an individual lane basis.
  • Data rate optimized equalization.
  • Operates over 7 meter of 24 AWG Twin-ax Cables up to 8 Gbps.
  • Typical residual deterministic jitter:.
  • 0.18 UI @ 8 Gbps w/ 30” of FR4.
  • 0.18 UI @ 5 Gbps w/ 40” of FR4.
  • 0.16 UI @ 2.5 Gbps w/ 40” of FR4.
  • 8 kV HBM ESD protection.
  • -40 to 85°C operating temperature range.
  • 7 mm x 7 mm 48-pin leadless LLP package.
  • Single power supply of either 3.3V or 2.5V.
