Description

The TC236P is a frame-transfer, charge-coupled device (CCD) image sensor designed for use in single-chip color NTSC TV, computer, and special-purpose applications requiring low cost and small size.

The image-sensing area of the TC236P is configured into 500 lines with 680 elements in each line. Twenty-two elements are provided in each line for dark reference. The blooming-protection feature of the sensor is based on an advanced lateral-overflow-drain concept. The sensor can be operated in a true-interlace mode as a 658(H) × 496(V) sensor with a low dark current. One important feature of the TC236P very high-resolution sensor is the ablity to capture a full 340,000 pixels per field. The image sensor also provides high-speed image-transfer capability. This capability allows for a continuous electronic-exposure control without the loss of sensitivity and resolution inherent in other technologies. The charge is converted to signal voltage at 13 u V per electron by a high-performance structure with a reset and a voltage-reference generator. The signal is further buffered by a low-noise, two-stage, source-follower amplifier to provide high output-drive capability.

The TC236P is built using TI-proprietary advanced virtual-phase (AVP) technology, which provides devices with high blue response, low dark current, high photoresponse uniformity, and single-phase clocking. The TC236P is characterized for operation from -10°C to 45°C.
