It uses an technology that achieves nearCCD image quality (based on onchip, phaselocked loop (PLL) to generate all internal signaltonoise ratio and lowlight sensitivity) while clocks from a single master input clock running between maintaining the inherent size, cost, and integration 6and 27 MHz. The maximum pixel rate is 84 Mp/s, advantages of CMOS. corresponding to a pixel clock rate of 84 MHz. A block The AR0543 sensor can generate full resolution image at diagram of the sensor is shown in Figure 1. up to 15 frames per second (fps). An on chip analogtodigital converter (ADC) generates a 10bit value for each pixel.

Once a row has been read, the data from the partitioned into three logical parts: columns are sequenced through an analog signal chain (providing offset correction and gain), and then through an A sensor core that provides array control and data path ADC.
