Termination Resistor Packs
Resistor packs are available with the values and the configuration required for LVDS and LVPECL
termination from Bourns, Inc. The part numbers are listed in Table 13. For pricing and availability
questions, please contact them directly at www.bourns.com.
3.4
Mixed I/O Systems
The use of different supply voltages and terminating resistors allows the OCX160 to support LVDS /
LVPECL translation as well as switching as outlined in Table 14.
