DS90LT012A, DS90LV012A www.ti.com SNLS141D – AUGUST 2002 – REVISED APRIL 2013 APPLICATION INFORMATION General application guidelines and hints for LVDS drivers and receivers may be found in the following application notes: LVDS Owner's Manual (SNLA187), 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 7.

DS90LT012A, DS90LV012A SNLS141D – AUGUST 2002 – REVISED APRIL 2013 www.ti.com Avoid 90° turns (these cause impedance discontinuities). Use arcs or 45° bevels. Within a pair of traces, the distance between the two traces should be minimized to maintain common-mode rejection of the receivers. On the printed circuit board, this distance should remain constant to avoid discontinuities in differential impedance. Minor violations at connection points are allowable.

DS90LT012A, DS90LV012A www.ti.com SNLS141D – AUGUST 2002 – REVISED APRIL 2013 FAIL-SAFE FEATURE The LVDS receiver is a high gain, high speed device that amplifies a small differential signal (20mV) to CMOS logic levels. Due to the high gain and tight threshold of the receiver, care should be taken to prevent noise from appearing as a valid signal.
