描述 Description

PTN3356 is a flash-based DisplayPort to VGA adapter optimized primarily for motherboardapplications, to convert a DisplayPort signal from the chip set to an analog videosignal that directly connects to the VGA connector. PTN3356 integrates a DisplayPortreceiver, a high-speed triple video digital-to-analog converter that supports a widerange of display resolutions, for example, VGA to WUXGA.
PTN3356 supports two DisplayPort lanes operating at either 2.7 Gbit/s or 1.62 Gbit/s perlane.
PTN3356 supports I²C-bus over AUX per DisplayPort standard, and bridges theVESA DDC channel to the DisplayPort Interface.
PTN3356 is powered from a 3.3 V power supply and consumes approximately 200 mW of powerfor video streaming in WUXGA resolution and 410 μW of power in Low-power mode. The VGAoutput is powered down when there is no valid DisplayPort source data being transmitted.PTN3356 also aids in monitor detection by performing load sensing on RGB lines andreporting sink connection status to the source.
