简  介:WM8148 12-bit/12MSPS CCD/CIS Analogue Front End/Digitiser Production Data, April 1999, Rev 4.0 DESCRIPTION The WM8148 is a 12-bit, 12MSPS analogue front end/ digitiser IC, which interfaces to colour or monochrome linear array CCDs or contact image sensors (CIS). The device includes all the signal conditioning circuitry required to process the analogue signals from the CCD or CIS prior to the internal ADC. Three signal-processing channels are included in the device. Each channel features reset level clamping, correlated double sampling (CDS), offset correction and programmable gain amplification (PGA). The output signal from each channel is then multiplexed into a high performance 12-bit analogue to digital converter (ADC). The reset level clamp and/or CDS functions can be selected or bypassed depending on the application. The WM8148 can be operated in several modes. The operational mode of the device, including the sampling scheme and power management is programmed via the serial/parallel control interface. Output data is presented in either 12-bit parallel or bytewide (8+4-bit) format. FEATURES Correlated double sampling Programmable gain amplifier Programmable input clamp voltage Offset correction 12-bit, 12MSPS ADC Internal voltage reference 12-bit or 8+4 bit data output mode Single 5V supply or 5V analogue/3.3V digital supply Programmable sample timing Control interface compatible with previous Wolfson AFEs 48-pin TQFP package APPLICATIONS Flatbed sca……
