PTN3356BS/F2MP
BL SECURE INTERFACES & POWER / Flash-based low-power DisplayPort to VGA adapter
Overview
PTN3356 is a flash-based DisplayPort to VGA adapter optimized primarily for motherboard applications, to convert a DisplayPort signal from the chip set to an analog video signal that directly connects to the VGA connector. PTN3356 integrates a DisplayPort receiver, a high-speed triple video digital-to-analog converter that supports a wide range 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 per lane.
PTN3356 supports I²C-bus over AUX per DisplayPort standard, and bridges the VESA DDC channel to the DisplayPort Interface.
PTN3356 is powered from a 3.3 V power supply and consumes approximately 200 mW of power for video streaming in WUXGA resolution and 410 μW of power in Low-power mode. The VGA output 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 and reporting sink connection status to the source.
