DESCRIPTION

The TSB15LV01 is a video signal processor integrated with a 1394 link layer controller. It is designed to be the center of a host-controlled, full-motion color camera when coupled with a 1394 PHY, CCD sensor and driver, analog front end, and an external EEPROM device. A camera based on the TSB15LV01 is compliant with the IEEE 1394a standard and the 1394 Trade Association’s Digital Camera specification, Draft 1.04.

The TSB15LV01 offers the advantage of 24-bit true-color digital video processing. This gives superior video quality at higher sustained data rates. Isochronous transfer of the video data and asynchronous control of the camera are accomplished via the 1394 high-speed serial bus, operating at data rates of up to 400 Mbits/s. This bus allows noncompressed full-motion digital video at rates of 30 frames/sec. Use of this serial connection eliminates the need for expensive video capture cards. The chipset supports the YUV 4:1:1, YUV 4:2:2, YUV 4:4:4, and RGB 24-bit formats.

The video signal processor (VSP) portion of the device incorporates proprietary digital image processing techniques, implemented with an advanced digital signal processing (DSP) ASIC. These techniques enable a camera to achieve excellent color accuracy and resolution. The use of a custom advanced CMOS ASIC process allows for both the advanced digital image processing techniques and for advanced color space conversion. This allows the multiple output formats required for a multipurpose video conferencing camera. Use of this advanced, low-power CMOS process also enables the camera to be powered by a notebook computer operating on battery power. The device is designed to work with CCDs that have a pixel resolution of 640(H) y 480(V). This resolution meets the VGA square pixel standards.

TSB15LV01 TSB15LV01I

SLLA216 – JUNE 2006

The 1394 link layer controller is capable of up to 400 Mbits/s operation and is compatible with both the IEEE 1394–1995 and 1394a standards. The TSB15LV01 implements all registers and address space required by the 1394 Trade Association’s Digital Camera specification, Draft 1.04 (hereafter referred to as the Digital Camera Specification).

The device supports packet speeds of up to 400 Mbits/s, but the maximum bandwidth consumed by the device is 200 Mbits/s. This means that a TSB15LV01-based camera leaves at least 200 Mbits/s available to other functions.
