Notes:

1.

The minimum tint is specified with the maximum 5.0MHz clock frequency.

2.

Tint is the line scan rate or integration time. It is the time between two start pulses. Hence, the minimum integration time is fixed by the highest clock frequency.

Here it is specified with a 4.0MHz clock frequency.

3.

Fclk is the main clock frequency, as is the pixel rate. Although the specification uses 4.0MHz, the module operates up to a maximum clock frequency of 5MHz.

4.

Vpavg = Σ Vp(n) / 704; where Vp is the pixel amplitude in volts and where n is sequential pixel number in one line scan.
