Table 5. Timing Symbols and Definition
Notes: 1. Clock pulse width varies with frequency, as it was explained foregoing paragraphs. 2. Prohibit crossing time to insure that two start pulses are not locked into the shift register during any single scan time. 3. Pixel delay times and settling time depend on the output amplifier. The numbers, which are given, are measured with an EL2044 amplifier. The faster the amplifier, the faster the signal will respond. In other words, faster rise and settle times are faster.
Output Circuits for Video Signal
The circuit in following page shows the PI3034A in a CIS module application. It also serves not only a reference for the above operational explanation given in note 3 under Table 2. Electro-Optical Characteristics it further exemplifies a method for interfacing the device in developing a 1728 element, A4 size CIS module.
