Note (3) FREQ is the input clock (CP) frequency and its corresponding PRATE is 2 X FREQ.
Where PRATE is the video pixel rate. The minimum rate for FREQ and PRATE should
be consistent with the maximum TINT, see note (5).
Note (4) DUTY is the ratio of the clock’s pulse width over its pulse period.
Note (5) 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 clock frequency. There must
be a minimum of (56+1204) clocks cycle between the two SP. 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 and determine the desired leakage tolerance level for the given
system.
Note (6) 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 control of ISO 9000 standards.
