NXP Semiconductors TDA4854
The TDA4854 is a high performance and efficient solution for autosync monitors. The TDA4854 provides synchronization processing, horizontal and vertical synchronization with full autosync capability, a TV/VCR mode and very short settling times after mode changes. The IC generates the drive waveforms for DC-coupled vertical boosters such as the TDA486x and TDA835x.| Part No. | TDA4854 |
