Product details
Overview
THS6214IPWPR from Texas Instruments is a dual-port, current-feedback differential line driver amplifier designed for VDSL2 and broadband PLC systems. It delivers >416 mA output current into 25-Ω loads, 43.2 VPP swing (±12 V, 100-Ω diff), –93 dBc HD3 at 1 MHz, and operates across ±5 V to ±14 V supplies. Used in central-office DSL line drivers supporting G.993.2 Profile 17a.
For engineers reviewing the THS6214IPWPR datasheet, THS6214IPWPR pinout, THS6214IPWPR application, or THS6214IPWPR equivalent, this page provides verified pin functions, bias-mode trade-offs (full/mid/low/shutdown), differential distortion performance, thermal design guidance for HTSSOP-24 PowerPAD™, and real-world VDSL2 system integration constraints.
Technical Context
The THS6214IPWPR implements a current-feedback architecture with independent dual ports (D1/D2 and D3/D4), each configurable via BIAS-1/BIAS-2 pins for full (100%), mid (75%), low (50%), or shutdown modes. Its IADJ pin enables fine-tuned bias current adjustment beyond discrete logic settings.
It achieves high linearity through optimized transimpedance gain (330–700 kΩ) and low noise (2.7 nV/√Hz voltage noise, 1.2 pA/√Hz noninverting current noise), while maintaining PSRR ≥50 dB at 1 MHz and crosstalk ≤–90 dB between ports under 1 MHz, 2 VPP conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±5 V to ±14 V - supports flexible power rail design in DSL line cards with ±12 V standard operation. |
| Output Current (DC) | ±416 mA into 25-Ω load - enables direct drive of twisted-pair lines without external current boosters. |
| Differential Output Swing | 43.2 VPP into 100-Ω differential load at ±12 V - provides wide dynamic headroom for high-line-power VDSL2 profiles (e.g., 17a). |
| 3rd-Harmonic Distortion | –93 dBc at 1 MHz, full bias - meets stringent MTPR requirements for G.993.2-compliant systems. |
| Small-Signal Bandwidth | 150 MHz at GDIFF = 10 V/V - ensures signal fidelity up to 30 MHz for central-office VDSL2 transmission. |
| Quiescent Current (per port) | 21 mA (full bias), 16.2 mA (mid), 11.2 mA (low), 0.8 mA (shutdown) - enables adaptive power management per line length. |
| PSRR | ≥50 dB at 1 MHz - suppresses supply noise coupling into differential output, critical for clean line signaling. |
Pinout & Package
The THS6214IPWPR is packaged in a 24-pin HTSSOP PowerPAD™ (PWP) with exposed thermal pad on underside, requiring connection to PCB ground plane for thermal integrity. Pin count and layout match TI's standard HTSSOP-24 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VS+, VS− | Positive/negative power-supply connections | Accept ±5 V to ±14 V rails; dual VS+ (pins 11, 24) and VS− (pins 1, 12) enable low-inductance decoupling. |
| BIAS-1/D1D2, BIAS-2/D1D2 | Port A bias mode control inputs (LSB/MSB) | Set D1/D2 amplifier bias level: 00 = full, 10 = mid, 01 = low, 11 = shutdown - no external pull-up/down required. |
| BIAS-1/D3D4, BIAS-2/D3D4 | Port B bias mode control inputs (LSB/MSB) | Independent control of D3/D4 amplifiers; allows asymmetric biasing for mixed-length line configurations. |
| IADJ | Adjustable bias current input | Analog pin enabling continuous reduction of quiescent current below discrete bias modes - used with external resistor. |
| D1 IN+, D2 IN+, D3 IN+, D4 IN+ | Noninverting inputs for each amplifier | High-impedance (500 kΩ || 2 pF) inputs accepting differential baseband signals from DACs or modulators. |
| D1 FB, D2 FB, D3 FB, D4 FB | Inverting inputs (feedback nodes) | Low-impedance (50 Ω) nodes for precision gain-setting networks; define differential gain GDIFF = 1 + RF/RS. |
| D1 OUT, D2 OUT, D3 OUT, D4 OUT | Differential output terminals | Capable of ±416 mA sourcing/sinking; require matched 100-Ω differential termination to maintain signal integrity. |
| GND | Control ground reference | Operates from VS− to (VS+ − 5 V); must be tied to stable system ground to ensure correct bias logic thresholds. |
| NC | No internal connection | Pins 18, 19 (HTSSOP) are unconnected - must be left floating or grounded per layout best practices. |
Key Features
| Feature | Design Value |
|---|---|
| Variable Bias Architecture | Four discrete bias modes plus analog IADJ adjustment - enables precise power/performance tuning per line segment length. |
| Dual Independent Ports | Two fully isolated amplifier pairs (D1/D2 and D3/D4) - supports simultaneous VDSL2 line driving with zero inter-port crosstalk impact. |
| High Output Drive Capability | 43.2 VPP swing into 100-Ω diff load at ±12 V - eliminates need for external output transformers in many DSL designs. |
| Low Distortion at High Frequency | –73 dBc HD3 at 10 MHz (full bias) - maintains spectral purity for multi-tone VDSL2 signals up to 17.664 MHz. |
| Thermally Enhanced Package | HTSSOP-24 PowerPAD™ with RθJB = 10.1°C/W - enables reliable 1-W+ continuous dissipation in compact line card layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS6222IPWPR | Single-port version; identical bias modes, noise, and distortion specs but half the channel count and 50% lower quiescent current per port. | Used where only one VDSL2 line per IC is needed - reduces component count in low-density line cards or evaluation boards. | Select THS6222IPWPR when board space or per-channel power budget is constrained and dual-port functionality is unnecessary. |
| THS6212IPWPR | Same dual-port architecture but rated for ±6 V to ±12 V supply range; lower max output swing (20 VPP) and reduced current drive (±250 mA). | Targeted for low-power ADSL2+ and shorter-loop VDSL2 deployments where full 43.2 VPP swing is not required. | Choose THS6212IPWPR for cost-sensitive, lower-power DSLAM modules operating at ≤12 dBm line power. |
Compared with THS6214IPWPR, THS6222IPWPR offers single-port simplicity and lower power, while THS6212IPWPR trades peak output capability for reduced supply voltage range and cost - all three share identical HTSSOP-24 packaging and bias control logic.

FAQ
What is the maximum continuous output current capability of the THS6214IPWPR?
The THS6214IPWPR delivers ±416 mA DC output current into a 25-Ω load at ±12 V supply, as specified in the Electrical Characteristics table (Section 6.5). Under transient AC conditions (>10 kHz), short-term current capability reaches approximately ±850 mA, enabling robust handling of VDSL2 burst-mode signals without clipping.
Does the THS6214IPWPR support both VDSL2 and ADSL2+ standards simultaneously?
Yes, the THS6214IPWPR is explicitly designed for VDSL2 systems and backward-compatible with ADSL, ADSL2+, and ADSL2++ standards per its Applications section. Its wide bandwidth (150 MHz), low distortion (–93 dBc HD3), and programmable bias modes allow it to meet line power and spectral mask requirements across all these DSL generations without hardware change.
How does the IADJ pin function in the THS6214IPWPR?
The IADJ pin on the THS6214IPWPR provides analog control over quiescent current, allowing fine-grained reduction beyond the four discrete bias modes set by BIAS-1/BIAS-2 pins. When an external resistor is connected from IADJ to VS−, it linearly scales bias current - enabling optimization for specific line lengths, temperature ranges, or power budgets not covered by fixed modes.
What thermal considerations apply to the THS6214IPWPR in HTSSOP-24 package?
The THS6214IPWPR in HTSSOP-24 (PWP) has RθJB = 10.1°C/W and requires connection of its PowerPAD™ to a thermally robust PCB ground plane. Without proper thermal vias and copper area, junction temperature may exceed 140°C limit for continuous operation. TI recommends ≥6 thermal vias under the pad and ≥2 in² of 2-oz copper for 1-W dissipation at 85°C ambient.
Can the THS6214IPWPR operate from a single supply?
No, the THS6214IPWPR is specified only for split-supply operation (±5 V to ±14 V). Its input common-mode range, output swing, and internal bias architecture require symmetric positive and negative rails. Attempting single-supply use violates Absolute Maximum Ratings and will result in undefined behavior or device damage.
