Typical Application (Internal Mode) CCD SERIAL INTERFACE DOUT DIGITAL IMAGE PROCESSING ASIC V-DRIVER HD, VD CLI V1–V4, VSG1–VSG8, SUBCK H1–H4, RG CCDIN AD9848/AD9849 INTEGRATED AFE+TD PBLK HBLK CLPDM CLPOB Figure 1b. Typical Application (External Mode) Figure 1a and 1b show the typical system application diagrams for the AD9848/AD9849. The CCD output is processed by the AD9848/AD9849’s AFE circuitry, which consists of a CDS, PxGA, VGA, black level clamp, and A/D converter. The digi- tized pixel information is sent to the digital image processor chip, where all post-processing and compression occurs. To operate the CCD, CCD timing parameters are programmed into the AD9848/AD9849 from the image processor, through the 3-wire serial interface. From the system master clock, CLI, provided by the image processor, the AD9848/AD9849 gener- ates the high speed CCD clocks and all internal AFE clocks. All AD9848/AD9849 clocks are synchronized with VD and HD. Figure 1a shows the AD9848/AD9849 used in Internal mode, in which all the horizontal pulses (CLPOB, CLPDM, PBLK, and HBLK) are programmed and generated internally. Figure 1b shows the AD9848/AD9849 operating in external mode, in which the horizontal pulses are supplied externally by the image processor. The H-drivers for H1–H4 and RG are included in the AD9848/ AD9849, allowing these clocks to be directly connected to the CCD. H-drive voltage of 5 V is supported in the AD9849. Figure 2 shows the horizontal and vertical counter dimensions for the AD9848/AD9849. All internal horizontal clocking is programmed using these dimensions, to specify line and pixel locations.
