Manufacturer:IR Description:The buffered CCD output is capacitively coupled to the VSP2232. The purpose of the input clamp is to restore the dc component of the input signal that was lost with the ac-coupling and establish the desired dc bias point for the CDS. Figure 1 shows the simplified block diagram of the input clamp. The input level is clamped to the internal reference voltage REFN (1.25 V) during the dummy pixel interval. More specifically, when both CLPDM and SHP are active, then the dummy clamp function becomes active. If the dummy pixels and/or the CLPDM pulse are not available in your system, the CLPOB pulse can be used in place of CLPDM as long as the clamping takes place during black pixels. In this case, both CPLDM pin (actives as same timing as CLPOB) and SHP become active during the optical black pixel interval, then the dummy clamp function becomes active. |
