ABSTRACT:
A logic system for charge-coupled device driver circuits includes a master oscillator for driving system logic circuits, which in turn generate signals for the non-bit-rate clock circuits. In addition, the system logic circuits generate a command which resets and synchronizes a separate resettable bit-rate oscillator to drive the bit-rate logic circuits which generate bit-rate clock waveforms. By maintaining separate oscillators for bit-rate and non-bit-rate functions, the logic system substantially reduces noise and therefore results in a clearer image from CCD area imaging array.
