8 / 28 page REV. 0 –8– AD9948 SYSTEM OVERVIEW CCD SERIAL INTERFACE DOUT DIGITAL IMAGE PROCESSING ASIC V-DRIVER HD, VD CLI V1–Vx, VSG1–VSGx, SUBCK H1–H4, RG CCDIN AD9948 INTEGRATED AFE + TD Figure 1. Typical Application Figure 1 shows the typical system application diagram for the AD9948. The CCD output is processed by the AD9948’s AFE circuitry, which consists of a CDS, a PxGA, a VGA, a black level clamp, and an A/D converter. The digitized pixel information is sent to the digital image processor chip, where all postprocessing and compression occurs. To operate the CCD, CCD timing parameters are programmed into the AD9948 from the image processor through the 3-wire serial interface. From the system master clock, CLI, provided by the image processor, the AD9948 generates the high speed CCD clocks and all internal AFE clocks. All AD9948 clocks are synchronized with VD and HD. All of the AD9948’s horizontal pulses (CLPOB, PBLK, and HBLK) are programmed and generated internally. The H-drivers for H1–H4 and RG are included in the AD9948, allowing these clocks to be connected directly to the CCD. H-drive voltage of 3 V is supported in the AD9948. Figure 2a shows the horizontal and vertical counter dimensions for the AD9948. All internal horizontal clocking is programmed using these dimensions to specify line and pixel locations.
