【Video Decoder Evaluation Board】

Video decoder serves as the system's primary gateway for perceiving external visual information, responsible for converting analogue video signals captured by cameras (such as CVBS) into digital video streams (such as YUV or RGB) that digital processors can interpret.

Renesas offers multiple video decoders tailored for diverse application scenarios. For instance, the TW9990AT-NA1-GR is an automotive-grade (AEC-Q100) video decoder featuring a 10-bit ADC. It supports converting analogue signals like NTSC/PAL into high-quality digital component video data. Its high-performance characteristics enable it to meet the stringent reliability and image quality demands of applications such as automotive surround-view systems.

For systems requiring simultaneous processing of multiple analogue video inputs—such as multi-camera surveillance or in-vehicle panoramic parking systems—Renesas' ISL79985/ISL79986 series, integrating four high-quality NTSC/PAL/SECAM video decoders, presents an ideal solution. Each channel features an independent 10-bit ADC and advanced image processing capabilities, significantly reducing luminance crosstalk noise within the image and ensuring the input quality of multiple video signals from the source.

【Video Switching Evaluation Board】

When systems require flexible management of multiple video sources (such as outputs from several decoders or inputs from multiple CSI cameras), the video multiplexer acts as the system's “traffic control centre”.

ISL59482 series video switch IC is specifically designed for this purpose. As a high-performance, dual-channel 4-to-1 multiplexing amplifier, each channel boasts a bandwidth of up to 520 MHz and extremely low propagation delay, enabling lossless switching and distribution of high-definition video signals. Its 2×4:1 configuration is ideally suited for dynamically allocating limited processing resources (such as a single video input interface) to multiple signal sources within video matrices, test equipment, or multi-display systems.

【CAT-5 Frequency Compensation Evaluation Board】

In large factories, car parks, or buildings, transmitting analogue video over low-cost, easily deployable CAT-5/6 network cables is a common solution. However, long-distance transmission causes significant attenuation of high-frequency signals, while electrical length variations between cables introduce signal skew. This ultimately results in blurred images, ghosting, or colour distortion.

MegaQ™ series adaptive equalizers (such as the ISL59601-ISL59605) specifically address this challenge. These chips automatically compensate for transmission losses over long distances in CAT-5/6 or RG-59 cables without requiring any manual adjustments. The highest-performance model, the ISL59605, compensates for up to 60dB @ 5MHz of cable loss, sufficient to support high-quality video transmission over distances of up to 1 mile of CAT-5 cable or 6000 feet of RG-59 cable while delivering high-quality video. Integrated automatic cable type identification, polarity detection, and ±3dB source amplitude variation compensation significantly simplify engineering deployment.
