PTN3356R1

PTN3356R1 ROM-based low-power DisplayPort to VGA adapter Rev. 2.2 — 16 August 2016 Product data sheet 1. General description PTN3356R1 is a ROM-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. PTN3356R1 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 (see Table 8). PTN3356R1 supports two DisplayPort lanes operating at either 2.7 Gbit/s or 1.62 Gbit/s per lane. PTN3356R1 supports I2C-bus over AUX per DisplayPort standard (Ref. 1), and bridges the VESA DDC channel to the DisplayPort Interface. PTN3356R1 is powered from a 3.3 V power supply and consumes approximately 200 mW of power for video streaming in WUXGA resolution and 410 W of power in Low-power mode. The VGA output is powered down when there is no valid DisplayPort source data being transmitted. PTN3356R1 also aids in monitor detection by performing load sensing on RGB lines and reporting sink connection status to the source. 2.
