TL1051 VIDEO PREPROCESSOR CIRCUIT SOCS032B – NOVEMBER 1991 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 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.
