NXP low-power DP-to-VGA adapter PTN3355 DP-to-VGA connectivity with best-in-class active and standby power As part of NXP’s industry-leading family of high-performance, robust DisplayPort-to-VGA adapters, this configurable device makes it easy to support legacy VGA interfaces while minimizing active and standby power consumption. KEY FEATURES ` VESA-compliant DisplayPort protocol converter ` DisplayPort HBR and RBR link rates ` Up to 2 DisplayPort lanes ` VSIS 1.2-compliant VGA output ` Analog VGA output up to pixel clock of 240 MHz ` Low active power: 200 mW ` Ultra-low standby power: 410 µW ` Application-friendly HVQFN package ` Factory-upgradeable firmware ` Commercial temperature range: 0 to +85 °C The NXP PTN3355 is a low-power DisplayPort-to-VGA adapter with an integrated 1:2 VGA switch optimized for system applications. It converts a DisplayPort signal from the system chipset to an analog video signal that goes directly to the VGA connector. KEY APPLICATIONS ` PC platforms: notebooks, desktop, tablet PCs ` Docking stations: PC and mobile platforms ` Dongles and adapters ` Embedded systems The PTN3355 uses a 3.3 V power supply. Power consumption is 200 mW for video streaming at WUXGA resolution and 410 µW in ultra low-power standby mode. The VGA output is powered down when there is no valid DisplayPort source data being transmitted. The PTN3355 also aids in monitor detection by performing load sensing on RGB lines and reporting sink connection status to the source. The PTN3355 integrates a DisplayPort receiver, a high-speed triple video DAC and a 1:2 VGA switch that supports a wide range of display resolutions, from VGA to WUXGA. The PTN3355 supports one or two DisplayPort lanes operating at either 2.7 Gbps (HBR) or 1.62 Gbps (RBR) per lane. EXTENSIVE PROGRAMMABILITY AND CONFIGURABILITY The PTN3355 is easy to configure using GPIO pins and/or internal configuration registers. The internal registers can be configured in the customer factory to support specific requirements. Also, to support firmware upgrades during manufacturing, NXP offers a Flash-over-AUX utility for use with Windows-based applications and, for applications that don’t use Windows, a Flash-over-DOS or Flash-over-I2C utilities. DEMONSTRATION PLATFORM The PTN3355 DPVGA demo board is a reference design that can be connected to a video source, such as a PC, and a VGA display.
