TL1051 Datasheet | Texas Instruments

TL1051 VIDEO PREPROCESSOR CIRCUIT - Solid-State Reliability - Supports Both Color and Monochrome Applications - Three Independent Channels Available for Use With RGB Monitors - Y Signal Generated From Three Independent Channels SOCS032B - NOVEMBER 1991 - Clamp Pulse-Select Option - White-Clip Function for Y Signal - Gain Control for R, G, B, and Y - Noise Suppression During Video-Blanking Periods description The TL1051 is a bipolar monolithic integrated circuit designed for use in preprocessing three channels of TI CCD image sensors. It receives video inputs from the TI TL1593 three-channel sample-and-hold circuit and outputs three processed channel signals and a single multiplexed Y (luminance) signal. Processing functions of the TL1051 include gain, automatic gain control, clamp, white balance, and white clip. The TL1051 is supplied in a 44-pin surface-mount plastic package and is characterized for operation from - 20°C to 45°C.

These circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 k V according to MIL-STD-883C, Method 3015; however, precautions should be taken to avoid application of any voltage higher than maximum-rated voltages to these high-impedance circuits. During storage or handling, the device leads should be shorted together or the device should be placed in conductive foam. In a circuit, unused inputs should always be connected...
