LVDS via Emulation

Started by Netoko Young July 4, 2007
Hi all,
 I've just read something about LVDS via emulation, in the datasheet
of the FPGA its specified that some banks natively support LVDS while
some other banks are specified to support LVDS in emulation only, does
this mean that to support LVDS an external resistor is needed?


Thanks,
Neto

Hi, BTW, here's the link to the datasheet: http://www.latticesemi.com/documents/tn1088.pdf?jsessionid=ba30dd372aa4$2137$E1 ps. its on page 13 and for correction its 'Differential output support via emulation'
