PTN3460BS/F4Y - eDP to LVDS Bridge IC | NXP Semiconductors
MPN： PTN3460BS/F4Y ✓ 啟用中PTN3460BS/F4Y 概覽
A display bridge IC sits in the video-signal-chain hierarchy between a graphics source and a display panel. As embedded DisplayPort replaced LVDS on chipsets and SoCs, bridge devices such as the PTN3460 became the standard way to keep legacy LVDS panels alive on new eDP-only platforms, performing both protocol conversion and configurable LVDS signal mapping.
Key features include two high-speed ports - a DisplayPort receive port facing the source and an LVDS transmit port facing the panel - full DP to LVDS protocol conversion, and programmable LVDS mapping that supports a wide variety of panel timing and mapping schemes without external glue logic. The single-chip integration of receiver, converter, and transmitter reduces BOM count and board area versus discrete solutions.
Internally, the PTN3460 processes the incoming DP stream, performs protocol translation, and transmits the processed stream in LVDS format. Configuration is stored on-chip, so the bridge powers up in a defined state and adapts to the connected panel. Support for embedded DisplayPort sources such as mobile and industrial chipsets makes it a natural fit for flat-panel designs migrating from LVDS-era panels.
Typical applications include industrial HMI panels, medical monitor displays, point-of-sale terminals, and embedded computing boards that pair modern eDP graphics outputs with LVDS panels. In each case the bridge eliminates a costly panel redesign when the graphics source transitions to eDP.
Design-wise, verify the LVDS mapping and timing configuration against the specific panel before layout freeze, and follow the NXP datasheet guidance for the 3.3 V rail decoupling and high-speed eDP lane routing.

典型應用
PTN3460BS/F4Y 適用於 6 應用s: Industrial HMI Displays, Medical Monitor Displays, Embedded Computing Boards, Point-of-Sale Terminals, Digital Signage Displays, Automotive Infotainment Development.
Industrial HMI Displays
Industrial human-machine-interface terminals frequently pair modern x86 or ARM compute modules that output embedded DisplayPort with long-lifecycle LVDS touch panels. The PTN3460BS/F4Y bridges this gap in a single HVQFN-56 chip: its DP receive port accepts the eDP stream from the chipset, and its LVDS transmit port drives the panel with programmable LVDS mapping that accommodates the varied timing schemes of industrial panels. Because the conversion is performed on-chip, designers avoid FPGA-based conversion logic and reduce BOM cost. The 0 C to +70 C rating covers typical factory-floor enclosures, and the 3.0-3.6 V supply integrates cleanly with standard 3.3 V rails already present on HMI carrier boards.
推薦
Medical Monitor Displays
Medical-grade monitors often retain qualified, certified LVDS display panels while their graphics sources migrate to eDP-only chipsets. The PTN3460BS/F4Y lets design teams update the compute platform without invalidating the display subsystem certification, since the bridge transparently converts the DP stream to the LVDS format the panel already accepts. On-chip programmable LVDS mapping supports the pixel and timing mappings used across medical panel families. The single-chip solution keeps the video signal chain simple, aiding documentation and risk analysis. Note that the 0 C to +70 C commercial rating requires thermal verification inside sealed medical enclosures; designs targeting wider ambience should verify junction temperatures against the NXP datasheet thermal data.
推薦
Embedded Computing Boards
Single-board computers and COM Express carrier boards must support a wide ecosystem of displays. Adding the PTN3460BS/F4Y beside an eDP-output SoC gives the board a second display interface - LVDS - broadening panel compatibility without extra firmware effort. The bridge performs DP to LVDS protocol conversion autonomously after configuration, and its two high-speed ports (DP receive, LVDS transmit) connect directly to the chipset lanes and panel connector respectively. Board designers route the eDP lanes as controlled-impedance pairs per the NXP datasheet layout guidance and supply the IC from the board's 3.3 V rail within its 3.0-3.6 V window. This makes the PTN3460 a low-risk way to extend display options on new board revisions.

Point-of-Sale Terminals
POS terminals and retail kiosks typically use commodity LVDS LCD panels driven by cost-optimized eDP-output chipsets. The PTN3460BS/F4Y converts between the two formats in one HVQFN-56 package, allowing procurement to keep sourcing the inexpensive, widely available LVDS panels even as chipset generations change. Its programmable LVDS mapping covers the single-pixel and dual-pixel panel variants common in the POS market, so one bridge part number can serve multiple panel SKUs in a product family. The 3.0-3.6 V supply range accepts the terminal's standard 3.3 V rail, and the 0 C to +70 C range suits typical indoor retail environments, keeping the video path simple, serviceable, and cost-effective.
推薦
Digital Signage Displays
Commercial digital-signage players are built around eDP-output media SoCs, yet many signage panel SKUs remain LVDS-interface designs with attractive pricing. The PTN3460BS/F4Y sits between the media SoC and the panel, receiving the DP stream and transmitting LVDS after on-chip protocol conversion. Its configurable LVDS mapping allows a single hardware design to be qualified against multiple panel vendors' timing definitions, reducing second-source risk for signage OEMs. Because the bridge operates from the player's existing 3.3 V supply and adds no firmware overhead to the media stack, integration effort is confined to layout and configuration validation. High-speed eDP lanes should be length-matched per the NXP PTN3460 datasheet recommendations to preserve signal integrity over the short source-to-bridge links typical of signage players.
推薦
Automotive Infotainment Development
Although the PTN3460BS/F4Y itself carries a 0 C to +70 C commercial rating and is not automotive-qualified, it is widely used on development benches and validation rigs for automotive infotainment systems, where eDP-output system-on-chip evaluation platforms must drive LVDS-based prototype display panels. The bridge converts the DP stream to LVDS with programmable mapping, letting display engineers exercise panel timing and mapping configurations quickly during bring-up. For bench use the 3.0-3.6 V supply is trivially met by lab 3.3 V rails. Production automotive designs must instead select NXP automotive-qualified display-bridge parts, but for pre-development panel validation the PTN3460 shortens iteration cycles at roughly $5.64 per unit as of 2026-10-20.

設計說明
Route the DisplayPort main-lane pairs from the source to the PTN3460 receive port as 100-ohm controlled-impedance differential pairs with length matching within the tolerances given in the NXP PTN3460 datasheet. Keep the pairs away from switching-regulator nodes and LVDS transmit lines. The same care applies to the LVDS transmit pairs running to the panel connector: short, matched, and referenced to a continuous ground plane. Excessive skew or impedance discontinuities on either link will appear as panel artifacts such as vertical streaking or intermittent link training failures.
Supply the PTN3460BS/F4Y from a clean 3.3 V rail within its 3.0 V to 3.6 V operating window. Place 100 nF ceramic decoupling capacitors at each supply pin pair plus one bulk 10 uF capacitor near the IC, per the datasheet typical application circuit. Avoid sharing the analog supply route with high-dcurrent loads such as panel LED backlight boost converters; backlight converters inject ripple that can couple into the LVDS output and cause visible noise on the display. Estimated: a 3.3 V rail with 3% tolerance stays safely within the 3.6 V maximum.
The /F4Y suffix defines a factory configuration variant - the LVDS mapping and related settings differ between PTN3460 suffixes such as /F4, /F6, and /F1MP. Substituting a different suffix part can leave the panel blank or mis-mapped even though the IC is pin-compatible. Before ordering an alternative, cross-check the suffix mapping table in the NXP PTN3460 datasheet against your panel's timing and mapping requirements. Also verify the 0 C to +70 C rating against the product's internal enclosure temperature, not the external ambient.
