sample and hold

The sample-and-hold signal generated by the NOCG is used to hold the analog output voltage of each pixel

constant until the next pixel is clocked out. The signal is sampled while CLK is high and held constant while CLK

is low.

nonoverlapping clock generators

The NOCG circuitry provides internal control signals for the sensor, including reset and pixel-charge sensing.

The signals are synchronous and are controlled by the outputs of the shift register.

initialization

Initialization of the sensor elements may be necessary on power up or during operation after any period of clock

or SI inactivity exceeding the integration time. The initialization phase consists of 12 to 15 consecutively

performed output cycles and clears the pixels of any charge that may have accumulated during the inactive

period.

output enable

The internally-generated output-enable signal enables the output stage of the sensor during the output period

(64 clock cycles). During the remainder of the integration period, the output stage is in the high-impedance state

that allows output interconnections of multiple devices without interference.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 1. Voltage values are with respect to the network GND.

2. Case temperature is the surface temperature of the plastic package measured directly over the integrated circuit.
