15 / 70 page  CS7620 DS301PP2 15 The output of the compander is available at the pins DOUT<9:0> and it makes transitions either at the falling or rising edges of the pixel rate clock CL- KO, controlled by a register bit. The Falling edge option is shown in Figure 14. Two options exist for outputting data. The first op- tion will output the pixel rate clock on the CLKO pin. The polarity of the pixel clock out of the pin is programmable so that the user may choose the ap- propriate clock edge to latch in the data. Based on the RD_OUT and HSYNC signals, the user will be able to determine when he is over active pixels. The second option will output a data_valid signal on the CLKO pin that is synchronous with the input clock (Figure 15). The data_valid signal will only toggle over active pixels. The user may then latch the data during this valid time. Note: DATA_VALID mode cannot be used if the system clock runs at the pixel rate. 3.4 Timing Generator There are three timing options available with the CS7620. The chip may produce all the vertical and horizontal timing for the imager, only the horizon- tal timing, or the chip may be used in a complete slave mode and not produce any of the CCD timing at all. Each will be discussed in detail in this sec- tion. 3.4.1 Vertical and Horizontal Timing Mode To select this option, the user must tie the BYPASS_PLL pin low and select the proper inter- nal timing mode in the timing mode register. The CS7620 is the master of the clocking. It will pro- vide vertical outputs and horizontal outputs. In this mode, the user must control two signals. The first is the master PWR_DN signal. When this signal is high, all of the CS7620 powers down except for the 1023 CODE_IN CODE_OUT 8191 X1 X2 X3 SLOPE1 SLOPE2 SLOPE3 SLOPE4 OFFSET2 OFFSET3 OFFSET4 OFFSET1 64 (x2,y2) (x1,y1) (x3,y3) Figure 13. 13-to-10 bit compander Figure 14.
