S/H and AGC for CCD Camera
Description The CXA1390AQ/AR are CCD camera's signal processing ICs which extract signals from the CCD output. These bipolar ICs perform correlated double sampling. AGC, color separation, high luminance detection and others. Additionary, these ICs are not affected by irregular pulses which occure during the CCD shutter mode. Featuers Pin compatible upgraded version of CXA1390Q/R which can be swapped out while using same peripheral chips Almost completely corrects irregular pulses and their negative affects Correlated double sampling function alllows for the suppression of low band noise in the CCD output AGC amplifier, which has High S/N ratio and wide gain control range, enhances the camera sensitivity Output for iris adjustment. High luminance detection output Usage of Vg (regulator) output allows for the formation of IRIS and AGC LOOP which are not affected by supply voltage functation Operating Conditions Supply voltage VCC CXA1390AQ 48 pin QFP (Plastic) CXA1390AR 48 pin LQFP (Plastic)
