DS50EV401 - 2.5Gbps / 5.0Gbps or 8.0Gbps Quad Cable and Backplane Equalizer

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.

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.

DS50EV401 2.5 Gbps / 5.0 Gbps or 8.0 Gbps Quad Cable and Backplane Equalizer DS50EV401 June 8, 2010 2.5 Gbps / 5.0 Gbps or 8.0 Gbps Quad Cable and Backplane Equalizer 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. The DS50EV401 uses Current-mode logic (CML) on both input and output ports, which provide constant 50 ohm singleended impedance to AC ground.
