Appendix E
LVDS Termination Resistors
E
Appendix D : DE3_HSTC Utility
This chapter describes the distribution of LVDS termination resistors on DE3 board. The I/O pins of
a HSTC connector on bank 2 and bank 3, which are used for differential transmitter channels,
support emulated LVDS via a termination resistor, as illustrated in
Figure E.1
. The following tables
list detailed distribution of termination resistors for each differential pin.
