TW6864, TW6868 Respond to Increased Demand for More
Integrated ICs for the Software Compression PC DVR Cards Used
in Security Surveillance Applications
Techwell, Inc. (Nasdaq:TWLL), a leading designer of mixed signal video semiconductor solutions for the security surveillance, automotive, and consumer electronics markets, today announced two multi-channel video capture products, the TW6864 and the TW6868. These devices feature Techwell's premium quality 4-in-1 video decoder technology -- which has the best weak signal performance in the industry, four high-performance audio ADCs, and an integrated PCI Express interface. This high level of integration simplifies the PC DVR card hardware design and reduces production costs.
Demonstrated at the CPSE show in Shenzhen, China earlier this week, the TW6864 and TW6868 take advantage of the significantly faster speed and overall larger data bandwidth of the PCI Express interface -- a feature in high demand for security surveillance systems utilizing a software compression PC DVR card.
The TW6864 and TW6868 support both real time and non-real time video and can output multiple video resolutions including D1, half D1, and CIF, providing maximum application flexibility. Techwell's proprietary video locking technology enables a non-real time switching speed that is faster than competitive products, allowing for the highest possible frame rate per channel. In addition, both ICs contain a high-performance proprietary DMA controller that fully utilizes the PCIe x1 bandwidth, enabling video and audio data transfer at an optimal throughput rate.
The TW6864 can decode and transfer four channels of real time D1 video (up to 16 channels of non-real time video) and four channels of audio. In comparison, the TW6868 can be cascaded with an external Techwell 4-in-1 decoder such as the TW2865 to achieve eight channels of real time D1 video and 9 channels of audio. In non-real time mode, the TW6868 (when combined with TW2865) can support up to 24 channels of video.
"The PCIe bus is becoming the dominant interface on the PC motherboard. Fortunately, the TW6864 and TW6868 provide a versatile and scalable solution for the software compression PC DVR card market," said David Nam, Techwell's VP of sales and marketing. "Techwell has set the precedent for highly integrated front-end surveillance video semiconductor solutions since 2001 and these two new video decoder solutions demonstrate why we continue to be the market leader."
