The VP2611 Video Compression Source Coder forms part of a chip set used in video conferencing, video telephony and multimedia applications. It produces data which conforms to the H261 standard for video compression with rates between 64K and 2M bits per second. With a 27 MHz clock the device will accept data produced to full CIF resolution at 30 Hz frame rates. The pipeline latency through the device is only 3 macro block periods.
