Notes:

(1)

The module will operate at 5.5MHz but its performance cannot be guaranteed.

(2)

The clock duty cycle is defined as the ratio of the high level duration divided by the duration of the clock period.

(3)

The tint (min.) is the lowest line integration time available at a 5.0MHz clock rate.
