much as 25 percent (see Fig. 2-1). When a 25-Gbit/s signal is transmitted on a line of an FR-4 printed circuit board (PCB) with a wiring length that differs by 1 cm, a phase difference of more than 1 bit occurs due to a deviation of 70 ps for 1-bit 40 ps. This greatly affects signal integrity (see Fig. 2-2). memory interfaces, require careful interface design on the PCB. Designers must address the timing and signal integrity requirements of these interfaces early in the design cycle.

PCB Breakout Routing for High-Density Serial Channel Designs Beyond 10 Gbps November 2011 Altera Corporation With a 1 mm (39.37 mil) ball pitch FPGA package, you can use two signal breakout routing options on the standard PCB fabrication technology that uses 4 mil minimum copper-to-copper clearances and a 10 mil drill with an 18 mil via pad. Therefore designers have to carefully use resistive termination. For PCB wires and cables, resistive termination is a com-mon technique because impedance matching is important to prevent the multiple reflection of signal wave.
