VP represents the average value Vp(n) for all n in line scans, where n is the sequential number of a pixel. This signal pixel level should be operated at less than
saturation levels, i.e., <1.3V.
VREF is used to adjust the video output bias. Under normal operation it is left unconnected.
FREQ is the input clock (CP) frequency and the pixel rate (PRATE). The minimum rate for FREQ and PRATE should be consistent with the maximum TINT, see
Note (5).
DUTY is the ratio of the clock’s pulse width to its pulse period.
TINT is the time interval between two start pulses (SP). Hence, if SP is generated from a clock count down circuit, it will be directly proportional to the clock
frequency. There must be a minimum of (56+1204) clock cycles between the two SPs. The longest integration time is determined by the degree of leakage current
degradation that can be tolerated by the system. A 10ms maximum is a typical rule-of-thumb. An experienced CIS user can use his discretion to determine the
desired leakage tolerance level for the given system.
TOP is a conservative engineering estimate. It is based on measurements of similar CIS modules. In production, they are measured under standard QA practices,
that is, under the control of ISO 9000 standards.
