LM1290
Description
The LM1290 is a high-performance, low-cost deflection solution for autosync monitors. The LM1290 provides full autosync capability, DC controls and plete freedom from manufacturing trims.
Key Features
- 22 kHz to 110 kHz with no ponent switching or external adjustments
- No manufacturing trims needed
- internal VCO capacitor trimmed on chip
- Sample-and-hold circuit for fast top-of-screen phase recovery, even when using posite sync
- DC-controlled H phase and duty cycle
- Resistor-programmable minimum VCO frequency
- Excellent jitter performance
- X-ray input disables H drive until VCC powered down
- Low VCC disables H drive (VCC < 8.5V)
- H output transistor protected against accidental turn on during flyback
