Product details
Overview
TS3DV520RHUR from Texas Instruments is a 5-channel differential 10:20 multiplexer switch optimized for HDMI v1.2a and DVI 1.0 digital video interfaces, delivering 2.4 GHz typical bandwidth, ≤0.1 ns bit-to-bit skew, 6 Ω max ON-state resistance, –41 dB typical crosstalk, and rail-to-rail 0–5 V switching across 56-pin WQFN package. It routes high-speed DVI/HDMI signals in AV receivers and HDTVs.
For engineers reviewing the TS3DV520RHUR datasheet, TS3DV520RHUR pinout, TS3DV520RHUR application, or TS3DV520RHUR equivalent, key selection criteria include differential channel count (5), bandwidth (2.4 GHz typ), Ioff partial-power-down support, HDMI/DVI compliance, and TQFN-56 thermal pad layout requirements.
Technical Context
The TS3DV520RHUR implements a single-select (SEL) controlled 10-input × 2-output per channel architecture, supporting bidirectional differential signal routing with matched ron(flat) ≤0.5 Ω and Δron ≤1 Ω across all 10 A-side inputs. Its design targets low-skew, low-crosstalk switching of serialized pixel data at up to 165 MHz pixel clock rates.
It features Ioff protection enabling safe partial-power-down operation, JESD 78 Class II latch-up immunity (>100 mA), and ESD robustness per JESD 22 (2 kV HBM, 1 kV CDM). All analog I/O ports operate rail-to-rail (0–5 V), while SEL accepts 0–0.8 V (L) / 2–5.5 V (H) logic levels under 3–3.6 V VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 2.4 GHz typical - supports HDMI 1080p/75 Hz and DVI SXGA without signal degradation |
| ON-state resistance | 6 Ω maximum - ensures minimal insertion loss and impedance matching for 100-Ω differential lines |
| Bit-to-bit skew | 0.1 ns maximum - preserves eye diagram integrity across all 10 data lanes in high-speed serial streams |
| Crosstalk | –41 dB typical at 250 MHz - prevents interference between active and adjacent differential channels |
| VCC range | 3.0–3.6 V - compatible with standard 3.3 V digital video subsystems and LDO-regulated supplies |
| Ioff current | 1 μA maximum at VCC = 0 - blocks backflow current during power sequencing or hot-swap scenarios |
| Input capacitance | 7.8 pF typical - minimizes loading on upstream drivers and preserves signal rise/fall times |
Pinout & Package
TS3DV520RHUR uses a 56-pin WQFN (RHU) package with 0.5 mm pitch, 10.85 × 11.15 mm body, 0.8 mm max height, and exposed thermal pad (Pin 57) requiring PCB soldering for thermal and mechanical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A9 | Differential input/output (data I/O) | 10 bidirectional analog ports grouped into five differential pairs (A0/A1, A2/A3, etc.) for HDMI/DVI TMDS channel routing |
| 0B1–9B2 | Differential output/input (data I/O) | 20 terminals forming ten differential outputs (e.g., 0B1/0B2), each paired with one A port under SEL control |
| SEL | Channel select input | Single CMOS-compatible control line determining whether An connects to nB1 (SEL = L) or nB2 (SEL = H) |
| VCC | Power supply | 3.0–3.6 V supply for internal logic and switch bias; multiple VCC pins ensure low-impedance distribution |
| GND | Ground reference | Multiple GND pins distributed across perimeter and center for return path integrity and noise suppression |
| NC | No internal connection | Unbonded pads (e.g., Pins 5, 27, 44, 46, 47, 52–55); must be left unconnected or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| HDMI v1.2a & DVI 1.0 compatibility | Validated for full 1080p/75 Hz and SXGA video formats with HDCP support - enables drop-in integration in certified consumer AV designs |
| Rail-to-rail analog switching | 0–5 V signal handling - accommodates both 3.3 V and 5 V TMDS swing without level-shifting circuitry |
| Low flat ON-resistance variation | ron(flat) ≤0.5 Ω and Δron ≤1 Ω - maintains consistent channel-to-channel timing and amplitude response |
| Partial-power-down support | Ioff ≤1 μA at VCC = 0 - allows safe isolation when upstream/downstream blocks are powered off independently |
| High-frequency signal integrity | –39 dB OFF isolation (OIRR) and 1.2 GHz small-signal bandwidth - suppresses leakage and preserves signal fidelity in dense PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential video multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3DV642RHAR | 64-pin WQFN, 6-channel, 3.5 GHz bandwidth, higher ICC (1.2 mA), supports 4K@30 Hz | Targets higher-resolution HDMI 2.0 applications; requires larger PCB footprint and tighter layout controls | Select when upgrading beyond 1080p/75 Hz or needing six independent differential channels |
| SN74CBT3245APW | 24-pin TSSOP, 8-bit FET bus switch, 5 V tolerant, no differential channel pairing, 250 MHz bandwidth | Suitable only for single-ended digital signal routing (e.g., I²C, GPIO), not HDMI/DVI differential video | Choose only for non-video, low-speed digital signal switching where differential integrity is not required |
Compared with TS3DV642RHAR, TS3DV520RHUR offers lower power (500 µA vs 1.2 mA) and smaller footprint (56 vs 64 pins) for 1080p systems; compared with SN74CBT3245APW, it delivers true differential channel matching, sub-0.1 ns skew, and HDMI-specific signal conditioning absent in general-purpose bus switches.

FAQ
What is the maximum data rate supported by the TS3DV520RHUR?
The TS3DV520RHUR supports a total raw capacity of 4.95 Gbps (single-link) with a typical bandwidth of 2.4 GHz and operation up to 165 MHz pixel clock rates. This enables full compliance with HDMI v1.2a and DVI 1.0 specifications for 1080p/75 Hz and SXGA video formats. The TS3DV520RHUR achieves this using low-skew, low-crosstalk differential switching architecture.
Does the TS3DV520RHUR require external termination resistors for HDMI/DVI operation?
No, the TS3DV520RHUR does not require external termination resistors for standard HDMI/DVI operation. Its internal design maintains 100-Ω differential impedance matching and low ON-state resistance (6 Ω max), allowing direct integration into TMDS signal paths without added components. The TS3DV520RHUR datasheet confirms proper signal integrity with standard 100-Ω PCB trace routing.
Can the TS3DV520RHUR operate with a 5 V input signal while powered from a 3.3 V supply?
Yes, the TS3DV520RHUR supports rail-to-rail analog I/O operation from 0 V to 5 V regardless of VCC (3.0–3.6 V), enabling interoperability with 5 V TMDS sources while using a 3.3 V system supply. This capability is explicitly specified in the Absolute Maximum Ratings and Recommended Operating Conditions tables for the TS3DV520RHUR.
How is thermal management handled for the TS3DV520RHUR in high-bandwidth applications?
The TS3DV520RHUR uses a thermally enhanced 56-pin WQFN package with an exposed metal pad (Pin 57) that must be soldered to a dedicated PCB thermal plane. With a θJA of 31.8°C/W, proper thermal pad connection reduces junction temperature rise during sustained 2.4 Gbps operation. The TS3DV520RHUR datasheet mandates this layout for reliable performance in HDMI/DVI applications.
Is the TS3DV520RHUR pin-compatible with other devices in the TS3DV family?
No, the TS3DV520RHUR is not pin-compatible with other TS3DV family members such as TS3DV642RHAR (64-pin) or TS3DV415RGZR (40-pin). Each variant has distinct pin count, pinout, and channel configuration. The TS3DV520RHUR's 56-pin WQFN layout is unique to its 5-channel, 10:20 architecture and must be implemented using its specific footprint and land pattern.
