The PTN3392BS,518 is a 2-lane Display Port to VGA Adaptor IC designed to connect a DisplayPort source to a VGA sink. The IC integrates a DisplayPort receiver and a high-speed triple video digital-to-analogue converter that supports display resolutions from VGA to WUXGA. It supports either one or two DisplayPort v1.1a lanes operating at either 2.7 or 1.62G-bit/s per lane. It has flash-over-AUX capability enabling simple firmware upgradability in the field. The PTN3392 supports I2C-bus over AUX per DisplayPort v1.1a specification and bridges the VESA DDC channel to the DisplayPort Interface. Designed for single supply and minimizes application costs. It can be powered directly from the DisplayPort source side 3.3V supply without a need for additional core voltage regulator. The VGA output is powered down when there is no valid DisplayPort source data being transmitted.
