The connector is an 8-pin 1mm surface mount flex input, Molex 52207-0890.
5.1 Inputs
There are five inputs:
• Clock is on Pin 6 of the I/O connector. This is main clock input into the CIS module.
• SP is on Pin 4. This is the start clock input to the CIS module.
• VDD is on Pin 2. This is a +5V supply.
• VN is on Pin 3. This is a -5V supply.
• VLED is on Pin 8. This is a +5V supply for the LED light source.
Note: Power return for the LED light source is GLED on Pin 7 and the ground return for the CIS modules is Pin 5.
5.2 Video Output
DIGOUT is on Pin 1 of the I/O connector. This 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 2.0MHz clock frequency. In operation, the time constants in the reference generator is set to match the initial exposure time, hence the
time constant will determine the optimum integration time. Note that the integration time is also a function of the clock frequency. Accordingly, it is highly
recommended that the parameters be factory adjusted for the specific applications. Although the specification is shown nominally at 2.0MHz, the maximum clock
frequency is 4.0MHz.
