Figures 4 and 5 show the initialization of the first sensor in relation to its subsequent cascaded sensors. The

Start Input Control (SIC) selects the first sensor to operate with 55 clock cycles of delay by connecting it to Vdd

on the first sensor and to Ground for all of the subsequent sensors. Hence the first sensor will operate with 110

inactive pixels being clocked out before its first active pixel is clocked out.
