TXV0106BQBR

Overview

The TXV0106BQBR is a 6-bit fixed-direction voltage translator in a 16-pin WQFN package. It supports dual supply voltages from 1.14 V to 3.6 V, enabling translation between logic levels such as 1.2 V, 1.8 V, 2.5 V, and 3.3 V. The device transmits data from the A bus to the B bus with a maximum data rate of 500 Mbps at 1.65 V to 3.6 V. It meets RGMII 2.0 timing specifications, featuring propagation delays as low as 1.1 ns, rise/fall times under 750 ps, channel-to-channel skew within ±400 ps, and duty cycle distortion below ±5%. Integrated features include a 10 Ω damping resistor, high drive strength up to 12 mA, and VCC isolation for power-down protection.

Feature Summary

• Fixed-direction data transmission from A bus to B bus with configurable symmetric dual-rail design
• Integrated 10 Ω damping output resistor to minimize signal reflections and improve impedance matching
• VCC isolation and disconnect functionality forces I/Os to high-impedance state during power anomalies
• Ioff circuitry prevents damaging current backflow during partial-power-down operations

Applications

• RGMII interface implementation between Ethernet MAC and PHY
• Medium or short range radar systems
• ADAS domain controllers
• HVAC controller designs
• Machine vision cameras

Procurement Notes

Verify the specific suffix 'BQBR' against the manufacturer's official ordering information to confirm the exact package type (WQFN) and tape-and-reel quantity. Ensure the component meets the required operating temperature range of -40°C to +125°C for your application environment. Cross-reference the datasheet revision history to confirm compatibility with your system design requirements.

Selection Notes

Select this component when strict timing constraints are required for skew-sensitive interfaces like RGMII. It is suitable for applications needing asymmetric voltage translation where data flows unidirectionally from lower to higher voltage domains. Consider the integrated damping resistor for signal integrity optimization without external components. Verify that the OE pin control logic aligns with your system's enable requirements.

Part Context

The TXV0106 belongs to Texas Instruments' family of low-skew, low-jitter voltage translators designed for high-speed digital interfaces. Unlike bidirectional translators, this device offers optimized performance for fixed-direction data paths. It addresses signal integrity challenges in mixed-voltage systems by providing precise timing characteristics and robust power isolation features essential for modern embedded and automotive electronics.

Replacement Considerations

Check for TXV0106 variants with different suffixes (e.g., PWR, PW) if alternative packages are needed. Ensure any substitute maintains the 6-bit width, fixed-direction architecture, and WQFN-16 footprint. Verify that replacement parts meet the same RGMII 2.0 timing specifications and thermal performance metrics.

FAQ

How does the TXV0106 handle power-down states?

The device supports partial-power-down mode via Ioff circuitry, which disables outputs to prevent damaging current backflow. Additionally, VCC isolation features force all I/Os to a high-impedance state if either supply voltage drops near zero.

What is the maximum data rate supported by this translator?

The TXV0106 supports data rates up to 500 Mbps when translating signals between 1.65 V and 3.6 V. For strict RGMII 2.0 compliance, the rate may be limited to 250 Mbps per channel depending on load conditions.
