ROM-based low-power DisplayPort to VGA Adapter

NXP introduces a ROM-based DisplayPort to VGA adapter optimized primarily for motherboard applications, PTN3356R1. The device is designed to convert a DisplayPort signal from the chip set to an analog video signal that directly connects to the VGA connector. PTN3356R1 also aids in monitor detection by performing load sensing on RGB lines and reporting sink connection status to the source.
