This slide reviews some of the design problems engineers face in the HD video market today. As mentioned earlier, HD video requires a bandwidth of up to 3Gb/s. In contrast, USB 2.0 which is used in most video product today only has a bandwidth 480mb/s, not enough to transmit HD video content without compression. However compression has several draw backs. First and foremost, compression degrades image quality. In addition, designing with compression ICs requires a larger bill of materials. Users will need an FPGA for the compression engine and DRAM for frame buffering. Compression also consumes additional engineering effort and design time. In addition, the market demands a small form factor for HD video products. Multiple chip solutions requires a larger PCB footprint, making miniaturization difficult. FX3 by Cypress offers solutions to these problems: FX3 provides 5GB/s bandwidth and can transmit HD video without a need for compression. FX3 is a one-chip solution that reduces PCB footprint and camera size. In the illustrations on the right side of the slide, a USB 2.0 2-chip solution for an HD video produces a low quality, compressed image whereas the FX3 one-chip solution produces a sharp, uncompressed HD image. Therefore, Cypress’s FX3 one-chip solution enables high definition images in small form-factor HD video products.
