11 PCB Design Guide Line f LVDS Interconnecting media between Transmitter and Receiver (i.e., connect, and cable) should be well balanced.(keep all these differential impedance and the length of media as same as possible.). Locate by-pass capacits adjacent to the device pins as close as possible. Minimize the distance between traces of a pair (S1) to maximize common mode rejection. See following figure. Place adjacent LVDS trace pair at least twice (>2 x S1) as far away. Avoid 90 degree bends. Minimize the number of VIA on LVDS traces. Match impedance of, connect, media (cable) and termination to minimize reflections (emissions) f cabled applications (typically 100. differential mode characteristic impedance). Use 4 layer PCB (minimum). Recommend the CITS series Si series of Polar Instruments company to the calculation of impedance Good No Good Monit Pad Stub Layer1 Signal Via Layer2 Via 11/12
