New LSI I.C. Leads the Way to 5V TV Sets

Two among many objectives that influ¿ence most of TV manufacturer choices are going to become the first in order of priority, they are: 1) utilization of very sophisticated multifunction IC in order to reduce to minimum calibrations, external components and assembling complexity 2) Reduction of total power consumption

Horizontal & Vertical Deflection Combinations for Monitors

Many of the integrated circuits for deflection utilized in monitors and video displays are TV application oriented. However, the monitor market is becoming more and more important, sufficiently so to justify the development of integrated circuits specifically aimed at satisfying the specific requirements of this field.

A new custom-made IC for monitors

The system evolution in the monitor field leads to the development of suitable ICs with performances and characteristics which are mainly monitor oriented rather than TV oriented. The automatic frequency raster preset of the monitors in computerised and optical equipment leads to the adoption of digital to analog converters in order to set the different parameters, and consequently all the regulations must be DC compatible. High scanning frequency and low jitter are additional factors that characterize the quality and the resolution of the monitors. New circuit solutions on silicon, concerning the monitor field, are described. In a single IC, the use of TTL compatible synchro pulses, horizontal and vertical processing functions and vertical ramp generation are implemented.<<ETX>>
