UNIT INTEGRATION TIME

Integration Timing:

The amount of time the CCD is exposed to light before clocking out the accumulated charge is called the integration time.

An RC circuit and Schmitt trigger inverter are used to set the unit integration time. Total integration time is a multiple of

the unit integration time.

INTEGRATE

The circuit is set to toggle at 100 Hz, providing a fixed unit integration time of 10ms. The actual integration time is set to a

multiple of the unit integration time using an internal integration counter in PLD2. The user can choose an integration time

from 10ms to 10 seconds by setting the integration switches appropriately (see Table 6: Integration Time Modes)

J6 INPUT CONNECTOR

This connector is used to input control signals to the evaluation board. This is an optional feature; all control lines can be

set via on-board switches. Images can be acquired using the on-board image capture button. No external digital inputs are

needed to acquire images.

J4 OUTPUT CONNECTOR

The J4 output connector provides 12 bits of video data in RS422 differential TTL format. J4, additionally, provides three

frame grabber sync signals in differential TTL format.

J7 INTEGRATION SYNC

This connector provides a sync signal that is high during the integration time period. The signal can be used to sync a

shutter or LED light source to the evaluation board, and can source up to 80mA at 5V.
