Product details
Overview
TS3DV520ERHURG4 from Texas Instruments is a 5-channel differential 10:20 multiplexer switch designed for HDMI v1.2a and DVI 1.0 digital video interfaces. It supports 1.9 Gbps data rate, 4.95 Gbps total raw bandwidth, and operates from 3 V to 3.6 V supply. Its rail-to-rail switching (0–3.6 V), low 0.1 ns max bit-to-bit skew, and –37 dB typical crosstalk make it suitable for high-definition audio/video receivers and HDTVs.
For engineers reviewing the TS3DV520ERHURG4 datasheet, TS3DV520ERHURG4 pinout, TS3DV520ERHURG4 application, or TS3DV520ERHURG4 equivalent, key selection criteria include HDMI/DVI signal integrity at 1080p/SXGA resolutions, differential channel count (5), ON-state resistance flatness (0.5 Ω typ), and QFN-42 thermal pad–enabled package compatibility with high-speed layout practices.
Technical Context
The TS3DV520ERHURG4 implements a single-select (SEL) controlled 20-bit-to-10-bit bidirectional analog multiplexer/demultiplexer architecture optimized for TMDS signaling. It routes five differential pairs (A0–A9 inputs ↔ B1/B2 outputs per channel) with simultaneous high-bandwidth pass-through and precise timing alignment.
Its design enforces rail-to-rail analog I/O operation across 0–3.6 V, maintains <0.5 Ω ron(flat) variation across input voltage range, and achieves 950 MHz small-signal bandwidth - enabling full compliance with HDMI 1.2a pixel clock multiplication (10×) and HDCP-compatible signal routing without degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential video multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3DV642RGER | 64-channel, 32:32 architecture; higher channel count but larger 64-pin WQFN package | Targeted at multi-input AV processors and video matrix switchers - not drop-in for 5-channel designs | Select only when scaling beyond 5 differential paths; requires PCB redesign and layout validation for 6+ GHz bandwidth |
| PI3USB30532ZLEX | USB 3.1 Gen1 + HDMI 2.0 dual-mode switch; supports 5.4 Gbps but adds USB protocol awareness | Used in hybrid docking stations where HDMI and SuperSpeed USB share physical connectors | Choose when co-routing USB 3.1 and HDMI is required; not recommended for pure HDMI/DVI-only systems due to added complexity |
Compared with TS3DV642RGER and PI3USB30532ZLEX, the TS3DV520ERHURG4 delivers optimal balance of channel density, thermal efficiency in 42-pin QFN, and proven 1.9 Gbps HDMI 1.2a performance - making it the preferred choice for cost-sensitive, space-constrained HDTV and STB designs.

FAQ
What is the maximum data rate supported by the TS3DV520ERHURG4?
The TS3DV520ERHURG4 supports a typical data rate of 1.9 Gbps with a total raw capacity of 4.95 Gbps for single-link HDMI/DVI. This enables full support for 1080p resolution at 75 Hz and SXGA (1280 × 1024) video formats, verified under recommended operating conditions (VCC = 3.3 V ± 0.3 V, TA = 25°C).
Does the TS3DV520ERHURG4 require external termination resistors for HDMI applications?
No, the TS3DV520ERHURG4 does not require external termination resistors. Its internal design maintains proper 100 Ω differential impedance matching across all channels, and its low 9 pF typical input/output capacitance ensures compatibility with standard HDMI 1.2a source and sink termination schemes without added components.
Can the TS3DV520ERHURG4 be used in HDCP-compliant systems?
Yes, the TS3DV520ERHURG4 is explicitly designed for HDCP-compatible signal routing. Its low skew (<0.1 ns), high bandwidth (950 MHz), and low crosstalk (–37 dB) preserve the integrity of encrypted TMDS streams, and TI confirms compatibility with HDCP 1.1/1.2 protocols in HDMI v1.2a implementations.
What is the role of the exposed thermal pad on the TS3DV520ERHURG4 package?
The exposed thermal pad on the TS3DV520ERHURG4 (RHU package) must be connected to GND for proper device operation. It provides critical thermal dissipation (θJA = 31.8°C/W) and reduces ground inductance, directly improving EMI performance and signal integrity for high-speed differential pairs routed through the TS3DV520ERHURG4.
How does the SEL pin control signal routing in the TS3DV520ERHURG4?
The SEL pin on the TS3DV520ERHURG4 selects between two differential output paths per channel: when SEL = Low, inputs A0–A9 connect to B1 outputs (0B1/0B2 through 9B1/9B2); when SEL = High, they route to B2 outputs. This single-control architecture simplifies system-level logic and eliminates timing mismatches between channel select signals.
