National LM1882-54ACT715 LM1882-R-54ACT715- R DATA SHEET
Summary
A highly programmable Video Sync Generator used by electronics engineers to create custom timing signals for display systems. This device accurately generates horizontal sync, vertical sync, composite blanking, and gating pulses for both interlaced and non-interlaced video modes. The comprehensive manual details deep configuration controls, allowing users to precisely set pulse widths, manage signal states through address registers, and adapt the generator's output characteristics regardless of system architecture or specific timing standards. Ideal for professional designers requiring maximum flexibility in video signal processing hardware.

Frequently Asked Questions
How do I start up the device initially?
The 'ACT715-R/LM1882-R' is optimized for easier start-up, as it defaults to a Clock Enable state, while the basic version defaults to a Clock Disable state.
What signals can this generator create besides standard sync signals?
It can generate separate or composite horizontal and vertical Sync, Cursor Blanking signals, and even Interrupt signals depending on the operating mode.
Is the device compatible with different video standards?
Yes. The 'ACT715-R/LM1882-R' is specifically mentioned as being better suited for applications using Hori-RS-170 timing (14.31818 MHz).
What are the limitations on the main Clock input?
The model has a maximum input clock frequency of > 130 MHz.
