Output pulse width is proportional to an 8-bit DATA input value. Two additional control inputs determine if the pulse is placed at the beginning, middle or end of the clock period. Pulse width and placement can be changed every clock cycle up to 60 MHz. Pulse width modulation is a well proven method for controlling gray scale and resolution enhancement in scanning laser print engines. Modulating pulse width provides the most cost effective method for continuous tone reproduction and resolution enhancement in low-to-moderate cost scanning electrophotographic systems. The AD9561 uses precision analog circuits to control dot size so that near-photographic quality images are practical without the high fi'equency clock signals required by all digital approaches. The AD9561 has improved features and performance over its predecessor, the AD9560. An improved ramp topology enables control of pulse width through 100% of the dot clock period as opposed to 95% for the AD9560. This enables smooth transition across dot boundaries for line screen applications. SEMIDEM LEMfTEM RElRACE TE Additionally, input data setup and hold time are symmetrical at 2 ns each, simplifying interface to the system bus. Finally, chip design and pinout are optimized to decrease sensitivity of analog circuits to digital coupling. (See layout section for detailed recommendations for optimum results.) Inputs are TTL or CMOS compatible, and outputs are CMOS compatible. The AD956lJR is packaged in a 28-lead plastic SOIC. It is rated over the commercial temperature range, O°C to +70°C. HIGHLIGHTS 1. 60 MHz native printer clock rate. 2. Single +5 V power supply. 3. On-chip Autocalibration. 4. Pulse placement flexibility. 5. High resolution: 256 pulse widths.
