5.1 Inputs
There are five inputs:
• Clock (CP): This is the input for the main sampling clock.
• SP: This is the start pulse input for initiating the scan.
• VDD: This is an input for the + 5V positive supply.
• VN: This is the input for the -5V negative supply.
• VLED: This is the input for the +5V power supply for the LED light source.
Note: Power return for the LED light source is GLED on Pin 13 &14, where as the rest of ground returns are on Pins 1, 2, 4, & 8.
5.2 Video Output
DIGOUT on Pin 3 of the I/O connector is the only output I/O. Pin 3 is the digital video output from the CIS module. Reflection off the
dark target produces a digital signal of “0” level, while the white reflection off the white target produces a digital level of “one”. The
amplitudes of the white and dark are listed in the table below:

Note:
1. The tint is specified with a 4.0MHz clock frequency. In operation the time constants in the reference generator are set to match the initial exposure time, hence the
generator’s time constant will determine the optimum integration time. Note, the integration time is also a function of the clock frequency. Accordingly it is highly
recommended that the parameters be factory adjust for the specific applications.
