The MC145481EN is an integrated circuit (IC) developed by Motorola Inc. for encoding and decoding digital signals. It is an excellent choice for applications needing low power, low cost, and versatility. This IC is typically used in digital audio, voice communications and automotive systems, where it is combined with µP platforms and various forms of communications.

The MC145481EN has extensive application fields, including digital audio (DA) systems, such as telephone and telephone extension line systems, cordless phones, and systems integrating voice recognition functions. Additionally, it is used in automotive systems to process audio data, and data conversion and control. Furthermore, the IC is based on the advanced SAW filter technology, which can provide good selectivity and efficiency. As a result, it is a highly suitable choice for all kinds of digital communications, including those for satellite phone systems, direct sequence spreading systems, cordless phones, and other voice communications systems.

The working principle of the MC145481EN is based on a pseudo-differential architecture. It has an array of processing elements, which enables it to carry out the encoding or decoding process one bit at a time. It does this by comparing the encoded bit with the reference sample in the input register. Then, the decoded bit is sent from the input register to the output register. Thus, it can process multiple bits to encode or decode the signal in one cycle.

The MC145481EN can provide an array of digital outputs, such as serial and parallel digital audio, voice-activated digital audio, voice dialing and more. Furthermore, its low power consumption and low noise make it an excellent choice for various applications. In addition to digital audio, it can also be used for signal conditioning, signal detection and measurement, modulator-demodulator signal processing, and firmware-controlled signal processing.

The MC145481EN is also easy to set up and configure, thanks to its built-in signal processing capabilities. It has a self-start feature, which allows it to be controlled from a host computer. Furthermore, its on-board test pulse generator makes it easy to carry out high-speed testing for signal quality and accuracy. Finally, it supports a wide range of software protocol formats, making it an ideal choice for many applications.
