Texas Instruments TS3DV642RUARQ1

Overview

TS3DV642RUARQ1 from Texas Instruments is an automotive-qualified, bidirectional 12-channel (6 differential) analog multiplexer/demultiplexer optimized for HDMI 2.0, DisplayPort 1.4 HBR2, MIPI DPHY/CPHY, and LVDS interfaces up to 6 Gbps. It operates from a single 3.3 V supply, delivers –1.6 dB insertion loss at 3.0 GHz, –17 dB return loss at 3.0 GHz, and –3-dB differential bandwidth of 5.8 GHz, enabling high-fidelity signal routing in ADAS camera and infotainment video paths.

For engineers reviewing the TS3DV642RUARQ1 datasheet, TS3DV642RUARQ1 pinout, TS3DV642RUARQ1 application, or TS3DV642RUARQ1 equivalent, this page provides verified electrical specifications, validated automotive-grade thermal performance (–40°C to 105°C), confirmed WQFN-42 wettable flank package mapping, and real-world HDMI/MIPI switching use cases with jitter and eye diagram impact data.

Technical Context

The TS3DV642RUARQ1 implements a passive FET-based switch architecture with integrated charge-pump drive, enabling low on-resistance (6.5–12 Ω) and flatness (<2.0 Ω) across 0–3.6 V common-mode range. Its functional modes-enabled via EN, SEL1, and SEL2-support discrete 1:2 or 2:1 channel selection, full-port A/B enablement, or Hi-Z power-down (6 μA).

It handles bidirectional differential signals with CMV 0–3.6 V and single-ended CMOS up to 5.5 V, while maintaining inter-pair skew ≤10 ps and intra-pair skew ≤8 ps at 1.7 GHz. IOFF protection ensures no back-powering when VCC = 0 V, critical for hot-swap automotive display systems.

Key Specifications

Pinout & Package

TS3DV642RUARQ1 is housed in a 42-pin WQFN package (3.5 mm × 9.0 mm, 0.5 mm pitch) with wettable flanks for automated optical inspection and enhanced solder joint reliability in automotive reflow profiles.

FAQ

What is the maximum data rate supported by the TS3DV642RUARQ1?

The TS3DV642RUARQ1 supports up to 6 Gbps per differential channel, validated for HDMI 2.0, DisplayPort 1.4 HBR2, and MIPI DPHY at 4.5 Gbps. Its 5.8 GHz –3-dB bandwidth and –1.6 dB insertion loss at 3.0 GHz ensure compliance with eye mask and jitter budgets for these standards. The TS3DV642RUARQ1 datasheet specifies 6.0 Gbps as the maximum data rate under recommended operating conditions.

Does the TS3DV642RUARQ1 require separate power supplies for analog and digital sections?

No, the TS3DV642RUARQ1 uses a single 3.3 V supply (VCC, Pin 1) for both analog signal path and digital control logic. It supports 1.8 V, 3.3 V, or 5.0 V logic levels on SEL1, SEL2, and EN inputs, but the core switch operation depends solely on the 3.3 V rail. This simplifies power design in automotive head units where only one low-noise 3.3 V rail is typically available. The TS3DV642RUARQ1 does not have separate AVDD/DVDD pins.

How does the TS3DV642RUARQ1 handle hot-plug detection (HPD) signals in HDMI applications?

TS3DV642RUARQ1 routes HPD signals bi-directionally on dedicated pins (HPD, HPD_A, HPD_B) with open-drain output structure compatible with HDMI specification. When used in 1:2 demux mode, HPD from the source passes through to either Port A or Port B based on SEL1/SEL2 state, enabling correct sink detection and EDID handshake. The TS3DV642RUARQ1 does not buffer or level-shift HPD-it preserves native 0–5 V signaling integrity across all three HPD paths.

Is the TS3DV642RUARQ1 pin-compatible with other members of the TS3DV642-Q1 family?

No, TS3DV642RUARQ1 is not pin-compatible with other variants such as TS3DV642RUKRQ1 (20-pin WQFN) or TS3DV642ZQNRQ1 (32-pin VQFN). The RUARQ1 variant uses a 42-pin WQFN package with unique pinout supporting full DDC, HPD, and CEC routing on both ports. Pin mapping differs significantly across package options, and migration requires PCB redesign. Always verify package-specific pin functions in the TS3DV642RUARQ1 datasheet before substitution.

What thermal performance can be expected from the TS3DV642RUARQ1 in a typical automotive PCB layout?

In standard 4-layer automotive PCBs with 2 oz copper and thermal vias to inner ground planes, the TS3DV642RUARQ1 exhibits a junction-to-board thermal resistance (RθJB) of 9.7 °C/W. At 45 μA active current and 3.3 V supply, power dissipation remains below 0.15 mW-resulting in negligible temperature rise (<0.1°C) above ambient. This allows placement near heat-sensitive image sensors or display drivers without thermal derating. The TS3DV642RUARQ1 thermal metrics are fully characterized per JEDEC JESD51 standards.
