A PC’s serial port provides signal lines that you can use to read voltage levels of digital circuits. You can use the port to test digital TTL (transistor-to-transistor-logic)-level circuits. You just ...

Serial-data links embed clocks in their data streams, and those clocks must be recovered at the receiver end. This Design Idea describes a data/clock-recovery algorithm for an NRZ (non-return-to-zero) ...

Audio Precision, makers of audio test and measurement gear, has introduced a new digital serial I/O module for its APx range of audio analyzers. The multichannel APx Digital Serial I/O option allows ...

Serial Peripheral Interface (SPI) output driver chips are popular with embedded designers because they provide multiple outputs without using any CPU I/O pins. This article explains how to adapt a ...
