Product details
Overview
THS6214IRHFR from Texas Instruments is a dual-port, current-feedback differential line driver amplifier designed for VDSL2 and broadband power line communications (PLC) systems. It delivers >416 mA output current into 25-Ω loads, 43.2 VPP differential swing with ±12-V supplies, and –93 dBc HD3 distortion at 1 MHz under full bias - enabling G.993.2 Profile 8b compliance and central-office transmission up to 30 MHz.
For engineers reviewing the THS6214IRHFR datasheet, THS6214IRHFR pinout, THS6214IRHFR application, or THS6214IRHFR equivalent, this page provides verified specifications, validated pin functions, confirmed VQFN-24 package mapping, real-world VDSL2/PLC use cases, and two technically documented alternative line drivers with explicit functional and bias-mode differences.
Technical Context
The THS6214IRHFR implements a current-feedback architecture with independent dual ports, each supporting selectable bias modes (full/mid/low/shutdown) via BIAS-1/BIAS-2 pins and fine-tuned quiescent current control via IADJ. Its differential output stage achieves high linearity with –70 dBc HD3 at 10 MHz and 70 dB MTPR under G.993.2 Profile 8b conditions.
It operates across ±5 V to ±14 V supplies, supports 100-Ω differential loads, and integrates PowerPAD thermal management. The device maintains PSRR ≥50 dB at 1 MHz and crosstalk ≤–90 dB between ports - critical for multi-line DSL transceivers requiring isolation and low inter-port interference.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | >416 mA into 25-Ω load - enables driving long DSL lines with minimal voltage drop and headroom preservation |
| Differential Output Swing | 43.2 VPP into 100-Ω differential load at ±12 V - supports >14.5 dBm line power per G.993.2 17a profile |
| Harmonic Distortion (HD3) | –93 dBc at 1 MHz, full bias - meets stringent VDSL2 spectral mask requirements for upstream/downstream channels |
| Small-Signal Bandwidth | 150 MHz at GDIFF = 10 V/V - ensures flat gain response across full VDSL2 band (up to 30 MHz) and PLC bands |
| Bias Control Flexibility | Four discrete modes (full/mid/low/shutdown) + IADJ pin - allows dynamic power scaling without external circuit changes |
| PSRR | ≥50 dB at 1 MHz - suppresses supply noise coupling into sensitive line driver outputs |
| Crosstalk | ≤–90 dB at 1 MHz - prevents signal leakage between dual ports in multi-pair DSLAM designs |
Pinout & Package
The THS6214IRHFR is packaged in a 24-pin VQFN (RHF) with 5.00 mm × 4.00 mm body size and exposed PowerPAD thermally connected to PCB ground plane. The PowerPAD is electrically isolated and must be soldered for thermal reliability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| BIAS-1/D1D2, BIAS-2/D1D2 | Port A bias mode control inputs (LSB/MSB) | Set full/mid/low/shutdown state for amplifiers D1/D2; logic thresholds: 0.8 V (low), 1.9 V (high) |
| BIAS-1/D3D4, BIAS-2/D3D4 | Port B bias mode control inputs (LSB/MSB) | Set full/mid/low/shutdown state for amplifiers D3/D4; independent of Port A for asymmetric configuration |
| D1 IN+, D2 IN+, D3 IN+, D4 IN+ | Noninverting inputs for four amplifiers | Accept differential baseband signals; input resistance = 500 kΩ || 2 pF |
| D1 FB, D2 FB, D3 FB, D4 FB | Inverting inputs (feedback nodes) | Configure gain via external RF/RS network; inverting input resistance = 50 Ω |
| D1 OUT, D2 OUT, D3 OUT, D4 OUT | Differential output terminals | Drive twisted-pair lines; output impedance = 0.2 Ω (differential, 1 MHz); short-circuit current = ±1 A |
| IADJ | Adjustable bias current control pin | External resistor sets quiescent current below mid-bias level - enables sub-11.2 mA/port operation |
| GND | Control ground reference | Range: VS– to (VS+ – 5 V); carries ≤1 mA per port in full bias - decouples bias logic from analog ground |
| VS+, VS– | Positive/negative supply connections | Support ±5 V to ±14 V operation; dual supply pins per rail ensure low-impedance return paths |
| NC | No internal connection | Pins 5, 16 (RHF); no routing or thermal tie required |
Key Features
| Feature | Design Value |
|---|---|
| Current-feedback architecture | Enables 150 MHz bandwidth with 10 V/V gain and stable operation into reactive DSL line impedances |
| Four-step bias control | Reduces total quiescent current from 84 mA (dual full bias) to <1.6 mA (dual shutdown) - extends system-level power budget |
| Differential distortion optimization | –93 dBc HD3 at 1 MHz and –73 dBc at 10 MHz (full bias) - satisfies G.993.2 spectral emission limits |
| High-output-voltage swing | 43.2 VPP into 100-Ω differential load - delivers >14.5 dBm line power without clipping in Profile 17a deployments |
| Thermal-enhanced PowerPAD | RθJB = 11.3 °C/W (VQFN) - sustains continuous 1-W dissipation with standard 4-layer PCB copper area |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS6222IRHFT | Single-port variant; identical bias modes, noise, and distortion specs; 50% lower quiescent current in full bias (10.5 mA/port) | Requires two devices for dual-port functionality; lacks integrated dual-port synchronization | Select when board space permits discrete port expansion or when independent thermal management per port is required |
| LMH6882EVM | Programmable-gain VGA with integrated ADC interface; higher noise floor (4.1 nV/√Hz); no IADJ pin or multi-bias logic | Targeted for receiver-side signal conditioning, not line driving; requires external output stage for >200 mA drive | Select only for hybrid transceiver designs needing variable gain before digitization - not a direct line driver replacement |
Compared with THS6214IRHFR, THS6222IRHFT offers identical per-port performance in a single-channel package but doubles component count for dual-line systems, while LMH6882EVM serves distinct signal-chain roles and cannot replace THS6214IRHFR's high-current differential drive capability.

FAQ
What is the maximum supply voltage range supported by the THS6214IRHFR?
The THS6214IRHFR supports a total supply voltage range of 10 V to 28 V, corresponding to ±5 V to ±14 V dual-supply operation. Absolute maximum ratings specify ±14 V on VS+ and VS– rails; operation beyond this risks permanent damage. The device maintains specified AC/DC performance across this full range, including full bias current and 150 MHz bandwidth at ±12 V.
How does the IADJ pin function in the THS6214IRHFR?
The IADJ pin on the THS6214IRHFR accepts an external resistor to further reduce quiescent current below the lowest factory-set bias mode (low bias = 11.2 mA/port). With RADJ = 0 Ω, it defaults to full bias; increasing RADJ linearly scales down bias current - enabling sub-10 mA/port operation while retaining functional amplification, unlike digital shutdown modes.
Which package does the THS6214IRHFR use, and what is its thermal performance?
The THS6214IRHFR uses the RHF package: a 24-pin VQFN measuring 5.00 mm × 4.00 mm with an exposed PowerPAD. Its junction-to-board thermal resistance (RθJB) is 11.3 °C/W, and maximum continuous junction temperature is 130 °C - requiring the PowerPAD to be soldered to a dedicated thermal pad on the PCB for reliable 1-W dissipation.
Can the THS6214IRHFR drive a 25-Ω load, and what is its output current capability?
Yes, the THS6214IRHFR is rated for >416 mA output current into a 25-Ω load with ±12-V supplies, delivering ±10.4 V per side (20.8 VPP single-ended) or 43.2 VPP differentially. This drive strength supports high-power DSL line termination and broadband PLC coupling networks without external boost stages.
What are the logic thresholds for the BIAS-1 and BIAS-2 pins on the THS6214IRHFR?
The BIAS-1 and BIAS-2 pins on the THS6214IRHFR have guaranteed logic thresholds of 0.8 V (maximum for logic low) and 1.9 V (minimum for logic high) over –40°C to +85°C ambient. These TTL-compatible inputs control full/mid/low/shutdown modes per port and draw ≤30 µA in logic-low state - compatible with standard GPIOs and open-collector drivers.
