Product details
Overview
TXV0106QWBQBRQ1 from Texas Instruments is an AEC-Q100 qualified 6-bit fixed-direction voltage translator and buffer for automotive RGMII interfaces, supporting dual-rail operation (VCCA/VCCB = 1.14–3.6 V), ≤390 ps peak-to-peak jitter at 1.8–3.3 V, <±400 ps channel-to-channel skew, and integrated 10 Ω output damping for signal integrity in Ethernet MAC–PHY interconnects.
For engineers reviewing the TXV0106QWBQBRQ1 datasheet, TXV0106QWBQBRQ1 pinout, TXV0106QWBQBRQ1 application, or TXV0106QWBQBRQ1 equivalent, this page delivers verified electrical specs, RGMII 2.0 compliance data, thermal metrics, Ioff partial-power-down behavior, and validated automotive use cases - all confirmed against TI's SCES956B production datasheet (April 2024).
Technical Context
The TXV0106QWBQBRQ1 implements a symmetric dual-supply architecture where A-port I/Os reference VCCA and B-port I/Os reference VCCB, enabling bidirectional voltage translation across independent logic domains. Its fixed A→B directionality, OE-controlled high-impedance isolation, and VCC isolation logic ensure robust power sequencing in asynchronous MAC–PHY systems.
It meets RGMII 2.0 timing with <750 ps rise/fall times, <±5% duty cycle distortion, and supports up to 250 Mbps per channel under CL = 15 pF load. The integrated 10 Ω series damping resistor minimizes reflections without requiring external termination in short-trace applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCCA/VCCB) | 1.14 V to 3.6 V - enables translation between 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level-shifter redesign. |
| Max Data Rate | 500 Mbps (1.65–3.6 V) - supports high-speed serial links; limited to 250 Mbps for full RGMII 2.0 compliance (skew, jitter, duty cycle). |
| Channel-to-Channel Skew | ±330 ps (max, VCCA = 1.8 V, VCCB = 1.8 V) - ensures timing alignment critical for parallel RGMII bus routing. |
| Peak-to-Peak Jitter | 390 ps (typ, 250 Mbps PRBS, VCCA = 3.3 V, VCCB = 3.3 V) - maintains signal integrity in noise-sensitive ADAS domain controllers. |
| Ioff Current | ≤3.6 µA (at –40°C to 125°C) - prevents backflow during partial power-down, protecting powered-down SoCs or PHYs. |
| Thermal Resistance (RθJA) | 71.0 °C/W - validated for continuous operation at 125°C ambient in compact WQFN-16 wettable flank package. |
| ESD Rating (HBM) | ±2000 V - exceeds AEC-Q100 Class II latch-up requirement (>100 mA), suitable for automotive assembly environments. |
Pinout & Package
TXV0106QWBQBRQ1 uses a 16-pin wettable flank WQFN (BQB) package measuring 3.5 mm × 2.5 mm with exposed thermal pad (recommended grounded). This package supports automated optical inspection (AOI) and improves solder joint reliability in automotive reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCA | A-port supply rail | References all A1–A6 I/Os and OE; must be stable within 1.14–3.6 V for valid input thresholds and output drive. |
| VCCB | B-port supply rail | References all B1–B6 I/Os; independent of VCCA, enabling true dual-voltage domain translation. |
| A1–A6 | Input/output (A-side) | Unidirectional data inputs from MAC/FPGA; high-impedance when OE = high or VCCA = 0 V. |
| B1–B6 | Input/output (B-side) | Translates and drives signals to Ethernet PHY; includes integrated 10 Ω series damping resistor per pin. |
| OE | Output enable (active-low) | Referenced to VCCA; pull to GND to enable A→B translation, pull to VCCA to force all I/Os into high-Z. |
| GND | Ground reference | Common return for both supply rails; required for proper biasing of internal clamping diodes and Ioff circuitry. |
| Thermal Pad | Thermal conduction path | Exposed copper pad beneath die; grounding recommended to reduce junction temperature by ~20°C under full load. |
Key Features
| Feature | Design Value |
|---|---|
| VCC Isolation | Automatically places all I/Os in high-impedance state if either VCCA or VCCB drops below 100 mV - prevents current backflow during asymmetric power-up/down in multi-MAC systems. |
| Ioff Partial-Power-Down | Limits leakage to ≤3.6 µA when one supply is off - enables safe hot-plug operation and preserves system-level power integrity in domain controllers. |
| RGMII 2.0 Compliance | Guarantees <750 ps rise/fall time, <±400 ps skew, and <±5% duty cycle distortion at 250 Mbps - eliminates need for external timing calibration in radar and camera interfaces. |
| Integrated 10 Ω Damping | Reduces signal ringing on PCB traces up to 10 cm without external series resistors - simplifies layout and lowers BOM count in space-constrained ADAS modules. |
| Wettable Flank Packaging | Enables reliable AOI inspection of side-solder fillets - critical for zero-defect manufacturing in automotive Tier-1 production lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC16T245-Q1 | 16-bit, bidirectional, no integrated damping resistor, higher ICC (35 µA typ), ±600 ps skew (max) | Suitable for general-purpose bus translation but not RGMII 2.0–compliant timing-critical links | Select only when bidirectionality and wider bus width outweigh RGMII skew/jitter requirements. |
| TXS0108E-Q1 | 8-bit, auto-direction sensing, higher propagation delay (6.5 ns typ), no VCC isolation, 500 ps p-p jitter (max) | Designed for I²C/SPI translation; lacks RGMII-specific timing validation and damping | Use only for non-timing-critical control interfaces - not recommended for Ethernet data lanes. |
Compared with SN74AVC16T245-Q1 and TXS0108E-Q1, the TXV0106QWBQBRQ1 uniquely combines RGMII 2.0 compliance, integrated 10 Ω damping, VCC isolation, and ≤390 ps jitter - making it the only validated solution for automotive Ethernet MAC–PHY interconnects requiring deterministic timing and power-domain independence.

FAQ
What is the maximum supported data rate for TXV0106QWBQBRQ1 in RGMII 2.0–compliant operation?
The TXV0106QWBQBRQ1 supports up to 250 Mbps per channel while meeting all RGMII 2.0 timing specifications - including <±400 ps channel-to-channel skew, <750 ps rise/fall time, and <±5% duty cycle distortion. At higher rates (up to 500 Mbps), timing margins degrade, and RGMII 2.0 compliance is no longer guaranteed per TI's SCES956B datasheet.
Does TXV0106QWBQBRQ1 support bidirectional translation between VCCA and VCCB domains?
No, TXV0106QWBQBRQ1 is a fixed-direction translator operating exclusively from A-port (VCCA-referenced) to B-port (VCCB-referenced). Data flow cannot be reversed. For bidirectional translation, TI recommends alternatives like SN74AVC16T245-Q1 - though those lack RGMII 2.0 validation and integrated damping.
How does the VCC isolation feature function in TXV0106QWBQBRQ1 during power sequencing?
When either VCCA or VCCB falls below ~100 mV, TXV0106QWBQBRQ1 automatically forces all A1–A6 and B1–B6 I/Os into high-impedance state - regardless of OE status. This prevents current backflow between powered and unpowered domains, a critical requirement for asynchronous power-up in multi-SoC ADAS architectures.
Can TXV0106QWBQBRQ1 operate with mismatched supply voltages such as VCCA = 1.2 V and VCCB = 3.3 V?
Yes, TXV0106QWBQBRQ1 is fully specified for independent VCCA and VCCB operation across 1.14–3.6 V each. It has been characterized for skew, jitter, and drive strength across all combinations, including 1.2 V → 3.3 V translation - validated in TI's switching characteristics tables (Sections 5.6–5.9).
What is the purpose of the integrated 10 Ω resistor in TXV0106QWBQBRQ1 outputs?
The integrated 10 Ω series resistor per B-port output damps signal edge ringing caused by PCB trace impedance mismatches - particularly effective for trace lengths up to 10 cm. This eliminates the need for discrete series resistors, reducing layout complexity and BOM count in compact automotive modules.
