Table 3. Recommended Operating Conditions @ 25oC
Notes:
1. Applies to all clocks; GBST, SIC, SI and CLK.
2. The dark level is set by the voltage on the VR input pad, which is internally set to a typical value of 0.7 volts.
Alternatively, if the user wishes to use a dark level greater than this, then VR can be supplied externally.
3. Although the device will operate with a pixel rate of less than 500 KHz, it is recommended that the device be
operated above 500 KHz to maintain performance characteristics. Operating below 500 KHz may result in a
significant integration of dark current.
4. Tint is the integration time of a single sensor and is the time between two Start Pulses. The minimum
integration time is the time it takes to clock out 29 inactive pixels and 344 active pixels. If several sensors are
cascaded together in a module then the minimum integration time is the time it takes to clock out 29 inactive
pixels and 344 active pixels from the first sensor and 344 pixels from each of all subsequent sensors, at a
given frequency.
5. The clock duty cycle is defined as the ratio of the positive duration of the clock to its period.
