Abstract :
Surface mount capacitors can be replaced with a buried capacitor in backplane interconnect applications requiring blocking capacitance, such as FiberChannel. This replacement improves cost, reliability and parasitic inductance. The smaller nominal capacitance value can be compensated for by using an equalizing receiver filter. Tradeoffs in capacitance choice are explained in detail. A nominal capacitance of around 1 pF provides a good choice for the analyzed scenarios.
