NRND DS90LV049H SNLS200A – SEPTEMBER 2005 – REVISED APRIL 2013 www.ti.com APPLICATION INFORMATION General application guidelines and hints for LVDS drivers and receivers may be found in the following application notes: LVDS Owner's Manual (lit #550062-003), AN-808 (SNLA028), AN-977 (SNLA166), AN-971 (SNLA165), AN-916 (SNLA219), AN-805 (SNOA233), AN-903 (SNLA034). LVDS drivers and receivers are intended to be primarily used in an uncomplicated point-to-point configuration as is shown in Figure 10.

NRND DS90LV049H www.ti.com SNLS200A – SEPTEMBER 2005 – REVISED APRIL 2013 TERMINATION Use a termination resistor which best matches the differential impedance or your transmission line. The resistor should be between 90 Ω and 130 Ω. Remember that the current mode outputs need the termination resistor to generate the differential voltage. LVDS will not work without resistor termination. Typically, connecting a single resistor across the pair at the receiver end will suffice.
