A comunicação digital é a espinha dorsal de qualquer sistema. Os dados de baixa frequência e de trânsito curto através de uma placa de circuito impresso (PCB) são normalmente simples. Mas quando os dados saem de uma placa, percorrem uma grande distância ou encontram interferência electromagnética (EMI), surgem desafios. Além disso, garantir dados fiáveis a altas velocidades requer uma atenção especial aos métodos de sinalização, linhas de transmissão, tratamento de erros e faseamento de relógio/dados. Inúmeros sistemas funcionam na bancada e depois falham no terreno devido a desafios ambientais. Os sistemas corretamente concebidos têm de sobreviver a EMI, descargas electrostáticas (ESD), alimentação variável e terrenos ruidosos.
Este não é um capítulo sobre teoria de comunicação de dados. A intenção é dar uma compreensão dos métodos amplamente utilizados para que os leitores possam tomar decisões informadas sobre qual interface usar ou onde precisam de uma linha de transmissão. Também é dada uma cobertura limitada a métodos mais antigos que os projectistas devem conhecer.
Comenta aqui a lógica CMOS. Não são apresentadas considerações especiais para outras famílias de lógica (RTL, TTL, ECL, etc.). Os métodos modernos colocam as funções lógicas no software do controlador ou em matrizes de portas programáveis em campo simples/dispositivos ...
