Introduction

The PEX8732-CA Redriver & Deskew component from Pericom is an interface component that provides up to 32 differential channels for high-speed data transmission between low-voltage differential signaling (LVDS) environments. It enables data transfer between differential levels of different voltage systems, allowing data ttransfer between 0.5 to 1.8V differential signaling systems up to 3.3V and beyond. It is specifically designed afor high-speed serial data applications such as video, audio, and data transmission. A sophisticated digital deskew algorithm performs an adjustable intra-axis slope matched equalization and adaptive equalization on each group of channels allows the PEX8732-CA to compensate for long cables, back-plane and PCB impedance mismatch.

Application Field

The PEX8732-CA is a versatile component that can be used in a wide range of applications. It can be used in audio/video distribution systems to help ensure clarity of reception and decrease noise. It can also be used in proprietary communication systems for data transmission which requires a more consistent signal and more reliable communication. Additionally, the PEX8732-CA can be used in home-theatre systems for smooth UHD/4K video and audio distribution.

The PEX8732-CA is an interesting component for resource-limited, low-power and high-speed applications such as in medical imaging, displays, and optical and machine vision. Other applications include imaging processors, automotive video systems, and video projection systems.

Working Principle

The PEX8732-CA is designed to operate in a differential environment, working simultaneously with a pair of complementary differential signals. The PEX8732-CA recognizes the peak voltage of the differential signals and converts it to a single-ended signal, which is then routed to the next stage for further processing. It utilizes a sophisticated Multi-Tap Deskew algorithm to automatically identify the optimum deskew setting on each channel to compensate for cable skew, and to ensure reliable signal integrity.

The PEX8732-CA also has an integrated equalizer which can be used to reduce signal loss due to signal attenuation and minimize channel-to-channel signal integrity variation. The equalizer\'s adaptive equalization feature is a software-calibrated configuration that compensates for different trace lengths and provides correct signal equalization. This equalization feature is specified to a maximum of 4.5dB of equalization.

Conclusion

In summary, the PEX8732-CA is an interface component that is designed for use in high-speed LVDS environments and provides up to 32 differential channels for serial data transmission. It incorporates a digital deskew and equalization algorithm that compensates for cable skew, length mismatch, and signal attenuation, and provides accurate, reliable signal transmission at high speeds. With its wide variety of applications, the PEX8732-CA Redriver & Deskew component from Pericom is the perfect choice for devices with limited power, limited space and requiring reliable high-speed data transmission.
