PTN3355 Low power DisplayPort to VGA adapter with integrated 1 : 2 VGA switch Rev. 3.1 — 4 November 2016 Product data sheet 1. General description PTN3355 is a DisplayPort to VGA adapter with an integrated 1 : 2 VGA switch 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. PTN3355 integrates a DisplayPort receiver, a high-speed triple video digital-to-analog converter and 1 : 2 VGA switch that supports a wide range of display resolutions, for example, VGA to WUXGA (see Table 9). PTN3355 supports either one or two DisplayPort lanes operating at either 2.7 Gbit/s or 1.62 Gbit/s per lane. PTN3355 supports I2C-bus over AUX per DisplayPort standard (Ref.
