OV420 companion asic product brief compact companion asic for medical imaging applications lead free available in a lead-free package the OV420 is a single chip solution for the ov6930- based medical applications. the OV420 provides an integrated analog-to-digital data conversion using a built-in a/d converter (adc), black level calibration (blc), lens correction (lenc), defect pixel correction (dpc), aec/agc and digital video parallel output (dvp). as shown in figure 2-1, the OV420 supports a standard sccb interface to communicate with the system and manipulate the above mentioned functions. during operation, the OV420 decodes the proprietary analog output from the ov6930 and digitizes it by an adc. the generated digital signals will then be processed by a digital signal processor (dsp) and finally, standard dvp outputs are sent out. find out more at www.ovt.com.
