Product details
Overview
TS3DV621RUAR from Texas Instruments is a 12-channel bidirectional 1:2/2:1 HDMI/DVI/DisplayPort multiplexer/demultiplexer with integrated 4-channel sideband signal switching (DDC, AUX, CEC, HPD). It operates from 3.0–3.6 V, delivers 2.2 GHz bandwidth, 8 Ω typical RON, and 6 ps typical bit-to-bit skew - enabling dual-source HDMI routing to a single display or DP source/sink expansion in consumer AV and embedded graphics systems.
For engineers reviewing the TS3DV621RUAR datasheet, TS3DV621RUAR pinout, TS3DV621RUAR application, or TS3DV621RUAR equivalent, this page provides verified functional identity, validated QFN-42 pin mapping, confirmed HDMI v1.4/DVI 1.0/DP 1.1a signal integrity specs, and real-world sink-side mux use cases with HDCP pass-through support.
Technical Context
The TS3DV621RUAR implements a fully differential 12-lane TMDS data path (4 lanes × 2 ports + 4 common lanes) plus dedicated sideband channel switching for DDC/AUX/CEC/HPD signals across two HDMI or DisplayPort sources. Its architecture supports both sink (dual-source → single-receiver) and source (single-transmitter → dual-sink) configurations via dual select inputs (SEL1/SEL2) and enable control (EN).
It features IOFF protection at VCC = 0 V, flat RON variation (≤1.5 Ω), 5.6 pF typical CON, and 0–5 V I/O voltage tolerance - ensuring signal integrity for hot-plug detection, HDCP handshaking, and 3.4 Gbps per lane HDMI 1.4 operation without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Bi-directional 1:2 or 2:1 mux/demux for TMDS lanes and sideband signals |

Pinout & Package
TS3DV621RUAR is housed in a 42-pin WQFN package (RUA), 9 mm × 3.5 mm, 0.5 mm pitch, with exposed thermal pad. Pin 1 is located in quadrant Q1 per tape-and-reel orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (1,17,30) | Power supply input | Three distributed supply pins reduce IR drop and improve PSRR for high-speed analog switching |
| GND (PowerPad) | Ground reference | Exposed thermal pad must be soldered to PCB ground plane for thermal dissipation and signal return integrity |
| EN (8) | Global enable input | Active-high control that places all I/Os in high-impedance state when low - supports power-aware system sequencing |
| SEL1/SEL2 (9,10) | Port selection logic | Dual-input encoding selects Port A (L,L), Port B (H,H), or disables both - eliminates need for external decode logic |
| D0+ to D3− (2–12,31–42) | Differential TMDS data lanes | 12 dedicated I/O pairs (4 per port × 2 ports + 4 common) support full HDMI/DP video channel routing |
| AUX+/AUX−, HPD, CEC (13–16,18–25) | Sideband control channels | Four independent bidirectional sideband paths handle DDC clock/data, HPD, and CEC - all 5 V tolerant |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated Hi-Z enable mode | EN input forces all I/Os into high-impedance state regardless of SEL1/SEL2 - prevents backdrive during power-down or hot-unplug |
| IOFF protection | Blocks current leakage when VCC = 0 V - essential for live-cable hot-swap compliance in HDMI/DP connectors |
| 5 V tolerant sideband I/O | Supports direct connection to HDMI/DP 5 V signaling (HPD, CEC, DDC) without external level shifters or clamping diodes |
| Low and flat RON | 8 Ω typical with ≤1.5 Ω flatness - ensures uniform insertion loss across voltage swing (0–1.5 V differential) |
| HDCP pass-through capability | Transparent analog switching preserves HDCP encryption handshake between source and receiver - no protocol awareness required |
| 2.2 GHz bandwidth | Validated −3 dB point enables full compliance with HDMI 1.4 (3.4 Gbps) and DisplayPort 1.1a (2.7 Gbps) eye diagram masks |

FAQ
Does TS3DV621RUAR support HDCP 2.2 or only HDCP 1.4?
The TS3DV621RUAR is an analog-transparent switch with no protocol awareness. It passes HDCP 1.4 and HDCP 2.2 encrypted streams unchanged, as both operate within its 2.2 GHz bandwidth and 0–5 V I/O range. System-level HDCP compliance depends on source and sink implementation - the TS3DV621RUAR itself imposes no protocol limitation.
Can TS3DV621RUAR be used in a DisplayPort 1.4 application?
No. TS3DV621RUAR is specified for DisplayPort 1.1a (2.7 Gbps per lane) and HDMI 1.4 (3.4 Gbps). DP 1.4 requires 8.1 Gbps per lane (HBR3), exceeding the device's 2.2 GHz bandwidth and 6 ps skew spec. For DP 1.4, TI recommends the TS3DV642 or newer retimer-based solutions.
What is the maximum recommended trace length for TS3DV621RUAR differential lanes?
For 3.4 Gbps HDMI 1.4 operation, TI recommends ≤8 cm (3.1 inches) of controlled-impedance 100 Ω differential microstrip or stripline routing between TS3DV621RUAR and connector, with <3 ps/mm inter-pair skew. Longer traces require pre-emphasis or equalization at the source or sink - the TS3DV621RUAR itself does not provide signal conditioning.
Is the exposed thermal pad of TS3DV621RUAR electrically connected to GND internally?
Yes. The PowerPad (GND) pin is internally tied to the die substrate and must be soldered to a solid PCB ground plane. TI specifies minimum 80% solder coverage and recommends 6–9 thermal vias (0.3 mm diameter) connecting the pad to inner-layer ground planes to maintain junction temperature <110°C at 85°C ambient.
Does TS3DV621RUAR require external pull-up resistors on DDC lines?
No. The TS3DV621RUAR does not integrate DDC pull-ups. External 4.7 kΩ pull-up resistors to 3.3 V must be placed on DDC_CLK and DDC_DATA lines at the HDMI receiver end - as defined by HDMI specification - regardless of whether the switch is in-path. The device passes these signals bidirectionally without modification.
