LM1290 Autosync Horizontal Deflection Processor
General Description
The LM1290 is a high-performance, low-cost deflection solution for autosync monitors.
The LM1290 provides full autosync capability, DC controls and complete freedom from manufacturing trims.
Its continuous capture range is from 22 kHz to 110 kHz (1:5).
Mode change frequency ramping, for protection of the horizontal deflection output
transistor, is programmable by using an external capacitor.
Together with the National Semiconductor LM1296 Raster Geometry Correction System for Multi-Frequency Displays, excellent performance is offered.
The two-chip solution provid...
