PTN3361CBSMP

Video Processing Overview

The PTN3361CBSMP is a high-speed level shifter that converts four lanes of low-swing AC-coupled differential input signals to DVI v1.0 and HDMI v1.4b compliant open-drain current-steering differential output signals, supporting up to 1.65 Gbit/s per lane for 1080p applications. It translates signaling from DisplayPort or PCIe electrical standards to TMDS-type DC-coupled differential current-mode signaling terminated into 50 Ω to 3.3 V on the sink side. The device operates from a single 3.3 V power supply (3.0 V to 3.6 V) and includes active buffering for HPD and DDC channels with voltage translation between 3.3 V source-side and 5 V sink-side.

Video Processing Feature Summary

• Converts low-swing AC-coupled differential inputs to DVI/HDMI compliant outputs with integrated self-biasing termination
• Provides active DDC buffering and level shifting with rise time acceleration for extended bus capacitance handling
• Includes I2C-bus slave ROM for mandatory HDMI dongle detection support via the DDET pin
• Features back-current-safe design on all sink-side terminals to prevent backdrive when unpowered

Video Processing Applications

• PC motherboard and graphics card display interfaces
• Docking station video output ports
• DisplayPort to HDMI dongles or adapters requiring deep color video format support
• DisplayPort to DVI dongles or adapters driving long cables

Video Processing Procurement Notes

Verify the specific ordering suffix MP indicates SMD dry pack packing method in Reel 13” Q2/T3 format. Confirm the temperature range covers -40 °C to +85 °C for ambient operation. Ensure the HVQFN32 package dimensions match the board layout requirements, specifically the 5 x 5 x 0.85 mm body size. Check that the exposed center pad connection strategy aligns with thermal and electrical ground requirements for proper device operation.

Video Processing Selection Notes

Select this component when interfacing multi-mode display sources using PCI Express or DisplayPort electrical configurations to sinks requiring standard DVI or HDMI electrical compliance. It is suitable for designs needing transparent level shifting without re-timing or software configuration. Consider its back-power safe characteristics for scenarios where the monitor remains powered while the source device is off. Ensure the system supports the required 3.3 V supply voltage and accommodates the necessary external components for REXT and EQ3 settings.

Video Processing Part Context

The PTN3361C series serves as an enhanced performance HDMI/DVI level shifter designed for multi-mode display source devices. It allows chipset vendors to implement reconfigurable I/Os supporting multiple display standards while minimizing the number of chipset I/O pins. The device enables support for DisplayPort, HDMI, and DVI standards through a single interface solution, facilitating compact and flexible display adapter designs.
