lvds_ch3Chapter 3 High-speed design 3.1 PCB layout tips As a technology, LVDS is relevant in systems where the data rates range from around 100 MHz to 2 GHz. At these frequencies a PCB can no longer be treated as a simple collection of interconnects. Traces carrying these high-speed signals need to be treated like transmission lines. These transmission lines should be designed with appropriate impedance and they need to be correctly terminated. The topics covered in this chapter range from impedance calculations and signal integrity to proper powersupply design. They are relevant for any high-speed design, whether it employs ECL, CML, or LVDS. Generalized design recommendations are provided next. The fast edge rate of an LVDS driver means that impedance matching is very important ……
