CRESCENTEC WEB CAM CONTROLLER MEETS USB 2.0 COMPLIANCE.Crescentec(R) Corporation, San Jose a company providing highly integrated ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. solutions for digital video and imaging devices, has announced that the CT-DC1100 web camera controller has been added to the Universal Serial Bus See USB. (hardware, standard) Universal Serial Bus - (USB) An external peripheral interface standard for communication between a computer and external peripherals over an inexpensive cable using biserial transmission. Implementers Forum (USB-IF) integrators list. The Crescentec DC1100 is a digital video controller which utilizes USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. 2.0 high-speed, high-bandwidth isochronous Time dependent. Real time voice, video and telemetry are examples of isochronous data. (communications) isochronous - /i:-sok'rn-*s/ A form of multiplexing that guarantees to provide a certain minimum data rate, as required for time-dependent data such as video or audio. pipe transfer, it provides 30 frames per second uncompressed video data at VGA resolution or operates at high resolution (SXGA (Super XGA) A screen resolution of 1280x1024 pixels. SXGA is commonly used on standard monitors, but provides a 1.25:1 aspect ratio, compared to the more common 1.33:1 (4:3) ratio. SXGA+ has a 1400x1050 resolution, which is an exact 1.33:1 ratio. See PC display modes. ) at 30 frames per second. The DC1100 is targeted specifically at mainstream CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. , mega-pixel CMOS web cameras and external video capture devices. "We are delighted to announce that the Crescentec DC1100 is the first USB 2.0 logo silicon in the isochronous category, and it is mainly designed for multimedia application," said Terry Jeng, vice president of Business Development. "To avoid the losses due to compression technology, the DC1100 streams 24MB per second uncompressed video data via USB 2.0, preserving the original video quality." About the CT-DC1100 The CT-DC1100 is a USB 2.0 compliant digital video image controller that offers a high quality, high performance and low cost tethered camera solution. Utilizing a high speed high-bandwidth isochronous pipe, it is able to provide 30 frames per second of uncompressed video data at VGA resolution, or 24 frames per second at SXGA resolution. Integrated on chip is a CMOS sensor interface module, a USB 2.0 high-speed device controller module, a UTMI UTMI USB 2.0 Transceiver Macrocell Interface UTMI Usb Transceiver Macrocell Interface compliant transceiver or Philips ISP1501 transceiver interface, an external serial EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. interface and general purpose I/O. To help software designers optimize their camera systems, Crescentec offers a software image enhancement filter that also allows the system designer to modify the video enhancement pipeline, Auto-Exposure algorithm and Auto-White-Balance algorithm. The DC1100 is housed in an 80-pin LQFP package. About Crescentec It is Crescentec's mission to provide high performance single chip solutions for various digital camera applications.
