NCN1188 http://onsemi.com 13 pcb design procedure implementing a high speed device requires careful design of signal traces to preserve signal integrity. the following electrical layout guidelines are basic rules to follow when designing boards capable of high speed transmission. ? the bypass capacitor must be placed as close as possible to the v cc input pin for noise immunity. ? the characteristic impedance of each high speed usb segment must be 45 . the characteristic impedance of each line is determined by (1) the distance between the signal trace and the inner layer ground plane of the pcb, as well as (2) the signal trace width. ? make the signal traces as short as possible to reduce losses through the pcb. furthermore, all corresponding d+ / d ? line segment pairs should be the same length. route d+ / d ? line segment pairs as close as possible for good common mode rejection. ? the use of turns or bends to route these signals should be avoided when possible. use 45 bends instead of 90 bends where bends are needed. the use of vias to route these signals should be avoided when possible. www.datasheet.co.kr datasheet pdf - http://www..net/
