PTN3393BSY

Overview

The PTN3393BSY is a DisplayPort to VGA adapter IC designed to connect a DisplayPort source to a VGA sink. It integrates a DisplayPort receiver and a high-speed triple video digital-to-analog converter supporting resolutions from VGA to WUXGA. The device supports one or two DisplayPort v1.1a lanes operating at HBR (2.7 Gbit/s) or RBR (1.62 Gbit/s). It features Flash-over-AUX capability for firmware upgradability, I2C-bus over AUX support, and bridges the VESA DDC channel. Powered by a single 3.3 V supply, it operates within a commercial temperature range of 0 °C to 85 °C in a 40-pin HVQFN package.

Feature Summary

• Supports VESA-compliant DisplayPort v1.1a conversion with main link rates up to 2.7 Gbit/s per lane.
• Integrates a triple 8-bit video DAC capable of driving standard 700 mV analog RGB signals.
• Enables field firmware upgradability via Flash-over-AUX functionality.
• Provides monitor presence detection through load sensing and HPD signal reporting.

Applications

• PC dongle accessories connecting DisplayPort outputs to RGB monitors
• Desktop and notebook computer display interfaces
• Notebook docking stations
