Overview
The PTN3356R1BS is a ROM-based, low-power DisplayPort to VGA adapter produced by NXP USA Inc. This component is primarily optimized for motherboard applications, designed to convert a DisplayPort signal from the chipset to an analog video signal that directly connects to a VGA connector.
The adapter integrates a DisplayPort receiver and a high-speed triple 8-bit video digital-to-analog converter, supporting a wide range of display resolutions up to WUXGA and a pixel clock rate of 240 MHz. It is powered from a 3.3 V power supply and features low power consumption, making it suitable for various computing devices.
