Overview
The PTN3355BS/F1528, produced by NXP USA Inc., is a low-power DisplayPort to VGA adapter with an integrated 1:2 VGA switch. This component is optimized primarily for motherboard applications, enabling the conversion of a DisplayPort signal from the chipset to an analog video signal that directly connects to the VGA connector. It integrates a DisplayPort receiver, a high-speed triple video digital-to-analog converter, and a 1:2 VGA switch, supporting a wide range of display resolutions up to WUXGA.
