PTN3360BBS,518

Overview

The PTN3360BBS,518 is a high-speed level shifter designed to convert four lanes of low-swing AC-coupled differential input signals into DVI v1.0 and HDMI v1.3a compliant open-drain current-steering differential output signals. It supports data rates up to 2.5 Gbit/s per lane with integrated 50 Ω termination resistors for self-biasing inputs. The device translates the Hot Plug Detect (HPD) signal from 5 V on the sink side to 3.3 V on the source side using non-inverting logic. Additionally, it provides passive level shifting for the DDC channel between 3.3 V and 5 V domains. Powered by a single 3.3 V supply, it consumes approximately 120 mW in active mode and features back-current-safe outputs.

Feature Summary

• Translates low-swing AC-coupled differential signals to DVI/HDMI compliant TMDS outputs
• Provides non-inverting voltage translation for the HPD signal across different power domains
• Features back-power safe design on all sink-side terminals to prevent backdrive current
• Supports transparent operation without requiring re-timing or software configuration

Applications

• Multi-mode display sources supporting DisplayPort, HDMI, and DVI standards
• HDMI and DVI interface level shifting in consumer electronics
• PCI Express PHY electrical configuration interfacing with display sinks

Procurement Notes

Verify the ordering suffix 'BS' corresponds to the HVQFN48 package variant SOT619-1 as specified in the datasheet. Confirm that the component meets RoHS compliance requirements for your specific manufacturing region. Ensure the supply voltage matches the recommended 3.3 V ± 10% operating condition to maintain signal integrity and proper functionality.

Selection Notes

Select this component when interfacing multi-mode display sources with DVI or HDMI sinks requiring voltage translation between 3.3 V and 5 V domains. It is suitable for designs needing transparent level shifting without data retiming. Consider the HVQFN48 package constraints and thermal pad soldering requirements for PCB layout. Verify that the application does not require higher speed performance than 2.5 Gbit/s per lane.

Part Context

The PTN3360B is functionally equivalent to the PTN3300A but offers enhanced speed and ESD robustness. It differs from the PTN3360A by providing non-inverting level shifting on the HPD channel instead of inverting. This device belongs to NXP's family of HDMI/DVI level shifters designed for multi-mode I/O implementations in display chipset vendors.

Replacement Considerations

PTN3360A serves as a functional alternative, though it provides inverting HPD level shifting rather than non-inverting. PTN3300A is also equivalent but operates at lower speeds and has reduced ESD resilience compared to the PTN3360B.
