Notes: 1. Saturation level is the maximum charge level before vertical transfer efficiency degradation (out of specification).
2. Saturation level is the maximum charge level before horizontal transfer efficiency degradation (out of specification).
3. Saturation level on output node can be optimized by running the readout register in MPP mode. Nevertheless, such a
method implies that the capacitances of the
Φ
L clocks are roughly 30% higher.
4. Measured with the Correlated Double Sampling (CDS).
5. Dynamic range is defined by the ratio of the saturation level to the temporal rms noise in darkness.
6. With a horizontal frequency maximum of 20 MHz, this value will be improved when decreasing this frequency.
