Overview
The PTN3355BS/F2, produced by NXP USA Inc., is a high-performance, low-power interface integrated circuit (IC) designed to convert DisplayPort signals to VGA signals. It 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. This IC 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.

Q & A
- What is the primary function of the PTN3355BS/F2 IC?
The PTN3355BS/F2 is designed to convert DisplayPort signals to VGA signals, making it suitable for applications requiring analog video output from a DisplayPort source.
- What are the supported DisplayPort lane configurations?
The IC supports one or two DisplayPort lanes operating at either 2.7 Gbit/s or 1.62 Gbit/s per lane.
- How does the PTN3355BS/F2 manage power consumption?
The IC consumes approximately 200 mW of power for video streaming in WUXGA resolution and 410 μW in Low-power mode. The VGA output is powered down when there is no valid DisplayPort source data being transmitted.
- What is the role of the integrated 1:2 VGA switch?
The integrated 1:2 VGA switch enables the driving of VGA signals to either the main board connector or the docking connector, helping to reduce the Bill of Materials (BOM) by eliminating the need for a discrete VGA switch component.
- How does the PTN3355BS/F2 support monitor detection?
The IC performs load sensing on RGB lines and reports the sink connection status to the source, aiding in monitor detection.
- What are the key benefits of using the PTN3355BS/F2?
The key benefits include high-speed data transmission, low power consumption, robust design with ESD protection, and versatile interface compatibility).
- Is the PTN3355BS/F2 recommended for new designs?
No, the PTN3355BS/F2 is currently in production but not recommended for new designs. Users are advised to contact the sales team for information on alternative or equivalent products).
- What industry standards does the PTN3355BS/F2 comply with?
The IC complies with VESA DisplayPort standards and supports I²C-bus over AUX, as well as VSIS 1.2 for video output modes).
- What is the pixel clock rate supported by the PTN3355BS/F2?
The IC supports a pixel clock rate up to 240 MHz).
- How can the firmware of the PTN3355BS/F2 be upgraded?
The firmware can be upgraded through the ‘Flash-over-AUX’ scheme and the I²C-bus interface).
