Product details
Overview
TS3DV520ERHUR from Texas Instruments is a 5-channel differential 10:20 multiplexer switch designed for HDMI v1.2a and DVI 1.0 digital video signal routing. It supports 1.9 Gbps data rate, 4.95 Gbps total raw bandwidth, rail-to-rail switching (0–3.6 V), 4 Ω typical ON-state resistance, and operates from 3 V to 3.6 V supply. It enables dual-HDMI-source selection in high-definition audio/video receivers.
For engineers reviewing the TS3DV520ERHUR datasheet, TS3DV520ERHUR pinout, TS3DV520ERHUR application, or TS3DV520ERHUR equivalent, key selection criteria include differential TMDS channel count (5), maximum data rate (1.9 Gbps), crosstalk (–37 dB typ), bit-to-bit skew (0.1 ns max), and QFN-42 (RHU) package compatibility with HDMI receiver PCB layouts.
Technical Context
The TS3DV520ERHUR implements a single-select (SEL) controlled 10-input × 2-output per channel differential multiplexer architecture, supporting bidirectional 10:20 signal routing across five independent TMDS lanes. Its low ron(flat) = 0.5 Ω typ ensures minimal signal distortion across the full 0–3.6 V I/O swing range.
It features rail-to-rail analog switching capability, 950 MHz small-signal bandwidth, –37 dB typical crosstalk at 250 MHz, and <0.1 ns output skew between channels - all optimized for HDMI/DVI pixel-clock-synchronous timing integrity up to 1080p/75 Hz and SXGA resolutions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 1.9 Gbps typical - supports HDMI v1.2a Type A and DVI 1.0 single-link video streams including 1080p/75 Hz. |
| Bandwidth | 950 MHz - preserves signal integrity for TMDS differential pairs carrying serial pixel data at >1.65 Gbps throughput. |
| ON-State Resistance | 4 Ω typical, 0.5 Ω flatness - minimizes insertion loss and voltage drop across differential channels under full-swing operation. |
| Crosstalk | –37 dB typical at 250 MHz - prevents interference between active and adjacent inactive TMDS lanes during multi-source switching. |
| Bit-to-Bit Skew | 0.1 ns maximum - maintains inter-lane timing alignment critical for HDMI/DVI eye diagram compliance and pixel clock recovery. |
| Supply Voltage | 3 V to 3.6 V - matches standard HDMI receiver core logic rails and enables direct interface without level-shifting. |
| ESD Rating | 14-kV HBM, 7.5-kV contact discharge - protects TMDS I/O pins against handling and system-level ESD events per IEC 61000-4-2. |
Pinout & Package
The TS3DV520ERHUR is housed in a 42-pin WQFN package (RHU), 9 mm × 3.5 mm, 0.5 mm pitch, with exposed thermal pad requiring connection to GND for thermal and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A9 | Differential input pair (10 total) | Accepts TMDS data/clock signals from two upstream sources (e.g., HDMI source 0 and source 1). |
| 0B1–9B1, 0B2–9B2 | Differential output pairs (20 total) | Routes selected source's TMDS signals to downstream HDMI receiver; B1/B2 denote path selection by SEL. |
| SEL | Single digital select control | Logic-high selects B2 outputs (source 2); logic-low selects B1 outputs (source 1); no internal pull-up/down. |
| VCC | Power supply | 3 V–3.6 V analog/digital supply; powers internal switch matrix and control logic; multiple VCC pins ensure low-impedance distribution. |
| GND | Ground reference | Common return for analog signal paths and digital control; exposed center pad must be soldered to GND plane. |
| N.C. | No internal connection | Unbonded pins (e.g., pins 27, 28, 44, 49, 50); must be left floating or tied to GND per layout best practice. |
Key Features
| Feature | Design Value |
|---|---|
| HDCP compatibility | Enables transparent switching of encrypted HDMI content without breaking HDCP authentication handshake between source and sink. |
| Rail-to-rail I/O switching | Supports full 0–3.6 V TMDS differential swing without clamping or distortion, preserving eye opening at 1.9 Gbps. |
| Low and flat ON-resistance | ron = 4 Ω typ with 0.5 Ω flatness ensures uniform insertion loss across all 10 data channels and both output paths. |
| Low input/output capacitance | CON = 9.8 pF typ minimizes loading on upstream TMDS drivers and preserves high-frequency signal integrity. |
| Latch-up immunity | Exceeds 100 mA per JESD 78 Class II - prevents destructive latch-up during hot-plug or transient overvoltage events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential video multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3DV642IRGZR | 64-channel, 32:64 configuration; higher channel count, larger 64-pin WQFN (RGE); supports up to 3.4 Gbps. | Targeted at multi-port HDMI switches (e.g., 4×1) rather than dual-source 1×2 routing. | Choose TS3DV642IRGZR only when scaling beyond two HDMI sources or requiring >2 Gbps data rate support. |
| PI3DBS16412ZLSEX | 16-channel, 8:16 mux; 3.3 V only; lower crosstalk (–45 dB); no HDCP-specific validation in datasheet. | Optimized for PCIe Gen3/USB 3.0 signal routing; lacks HDMI/DVI-specific compliance testing documentation. | Consider PI3DBS16412ZLSEX for non-HDCP systems where ultra-low crosstalk outweighs HDMI protocol assurance. |
Compared with TS3DV642IRGZR and PI3DBS16412ZLSEX, the TS3DV520ERHUR delivers optimal balance of HDMI v1.2a compliance, dual-source simplicity, 4.95 Gbps aggregate bandwidth, and QFN-42 footprint - making it the preferred choice for cost-sensitive, space-constrained 2×1 HDMI switch designs.

FAQ
What is the maximum data rate supported by the TS3DV520ERHUR?
The TS3DV520ERHUR supports a typical data rate of 1.9 Gbps per TMDS lane, enabling full compliance with HDMI v1.2a and DVI 1.0 single-link specifications including 1080p/75 Hz video. Its 950 MHz bandwidth and low skew ensure reliable eye diagram margins at this rate. The TS3DV520ERHUR achieves 4.95 Gbps total raw capacity across all five differential channels.
Does the TS3DV520ERHUR require external termination resistors for HDMI applications?
No, the TS3DV520ERHUR does not require external termination resistors on its TMDS I/O ports. Its internal design maintains proper 100 Ω differential impedance and low capacitance (CON = 9.8 pF typ), allowing direct connection to standard HDMI source and sink ICs without added components. The TS3DV520ERHUR's ron flatness and low crosstalk eliminate need for board-level termination tuning.
How is HDCP compatibility implemented in the TS3DV520ERHUR?
The TS3DV520ERHUR is designed to be transparent to HDCP signaling: it passes DDC (I²C) and CEC traffic unaltered while switching TMDS video/audio streams. Its rail-to-rail analog switching and sub-0.1 ns skew preserve HDCP authentication handshake timing and pixel clock integrity. TI validates the TS3DV520ERHUR for HDCP compatibility in reference designs, confirming no re-authentication delay or failure during source switching.
What is the recommended PCB layout practice for the exposed thermal pad on the TS3DV520ERHUR?
The exposed center pad of the TS3DV520ERHUR must be soldered to a solid GND plane using ≥4 thermal vias (0.3 mm diameter, spaced evenly). TI recommends a 69% solder paste coverage area under the pad and a non-solder-mask-defined (NSMD) land pattern per SLUA271 guidelines. Improper grounding of this pad risks thermal throttling and increased crosstalk - both verified in TS3DV520ERHUR characterization reports.
Can the TS3DV520ERHUR operate with a 2.5 V supply voltage?
No, the TS3DV520ERHUR requires a minimum VCC of 3 V and is specified only for 3 V to 3.6 V operation per its absolute maximum and recommended operating conditions. At 2.5 V, the internal switch transistors fail to fully enhance, causing elevated ron (>12 Ω), degraded bandwidth (<500 MHz), and potential signal clipping. The TS3DV520ERHUR datasheet explicitly prohibits operation below 3 V to guarantee HDMI/DVI timing compliance.
