PCM3168A, a pulse code modulation/time division multiplexing (PCM/TDM) digital signal processor (DSP) series, is developed for use in applications such as HDMI, DisplayPort, high-definition television (HDTV) audio, and set-top box products. It provides a cost-effective solution for interfacing between a digital video or audio circuit and a software-controlled audio or video processor.

The PCM3168A is a low-power, low-cost DSP designed for multimedia applications. The DSP consists of a programmable core and three interfaces: an audio interface, an I2S (inter-integrated circuit sound) interface and an HDMI interface. There are four types of audio codecs supported by the PCM3168A, which are PCM, Dolby Digital, DTS, and E-AC-3. It also supports two PCM bit depths: 24-bit and 16-bit. It is available in two versions, the P3168A and P3168APAP, which differ in their number of inputs and outputs.

PCM3168APAP application field includes audio and video applications such as gaming consoles, digital TV, digital signage, and home theater systems. It can be used in a variety of digital audio and video applications such as HDTV receivers, Set-top Boxes, IPTV gateway servers, HD video conference systems, and others. It is suitable for use in both current and future digital audio applications.

The working principle of PCM3168APAP is to convert analog audio signals into their digital equivalent. The analog signals are first converted into a digital binary format through a process called pulse code modulation (PCM). The PCM data can then be transferred and stored digitally to a memory device such as a hard drive, CD-Rom, and/or other storage mediums. The PCM data can then be reconstructed into its original analog format, with digital-to-analog converters. PCM3168APAP also includes digital signal processing (DSP) functions such as digital filters, digital crossovers, frequency and amplitude correction, and low latency audio de-noising.

PCM3168APAP also enables advanced audio and video processing by providing advanced user selectable features such as tone control, dynamic wide range, digital signal mixing, and digital decoding/encoding. Furthermore, PCM3168APAP features various automatic features, such as digital signal mixing, output gain control, and limiter compression. With the PCM3168APAP, many different audio signals can be processed with precision and accuracy.

The PCM3168APAP is designed to address the requirements of modern digital audio and video solutions. Its highly configurable design allows rapid system development and a comprehensive support for maximum audio and video quality. In addition to its excellent signal processing capabilities, the PCM3168APAP is fully compatible with HDMI and I2S interfaces. It also provides a wide range of output formats such as stereo, 5.1, 7.1, or multi-channel surround. This makes it the ideal choice for audio signal processing solutions.
