Virtex-E/-II/-II Pro/-4/-5, Spartan-IIE I/O - Can these devices receive nondifferential LVPECL signals with a differential CLK connected to a GCLK pin?

描述

Can Virtex-E/-II/-II Pro/-4/-5/-6 or Spartan-IIE devices receive or transmit nondifferential (single-ended) LVPECL signals?

解决方案

No. There is no support for nondifferential (single-ended) LVPECL signals.

These devices may be able to drive only non-differential LVPECL signals. However, this is not a supported flow as it is up to the designer to set and regulate the voltage levels.

These devices cannot receive nondifferential LVPECL signals, and cannot receive a nondifferential LVPECL clock on a global clock pin.
