NXP Semiconductors TDA4855
The TDA4855 is a high performance and efficient solution for autosync monitors. The concept is fully DC controllable and can be used in applications with a microcontroller and stand-alone in rock bottom solutions. The TDA4855 provides synchronization processing, H + V synchronization with full autosync capability, and very short settling times after mode changes.| Part No. | TDA4855 |
