Product details
Overview
THS6302IRHFR from Texas Instruments is a dual-port, current-feedback differential line driver IC designed for G.Fast 212-MHz DSL systems and backward-compatible with VDSL-30a, VDSL-17a, ADSL2+, and G.mgFast 424-MHz profiles. It delivers 80 mA linear output current, 11 V/V differential gain, and supports 8 dBm line power up to 212 MHz with MTPR of 48 dBc in G.Fast 212-MHz mode - deployed in central office (CO) DSL line card designs.
For engineers reviewing the THS6302IRHFR datasheet, THS6302IRHFR pinout, THS6302IRHFR application, or THS6302IRHFR equivalent, key selection criteria include multitone power ratio (MTPR) across DSL profiles, programmable bias modes (9 configurations), adjustable quiescent current via IREF resistor, dual-channel crosstalk performance (<75 dB at 212 MHz), and VQFN-28 thermal management capability.
Technical Context
The THS6302IRHFR implements a dual-channel current-feedback amplifier architecture with internally fixed 11 V/V gain and 10-kΩ differential input impedance. Each channel features independent 2-pin three-level logic control (Mx1/Mx2) enabling nine discrete bias modes - including G.Fast 212-MHz (39 mA/ch), G.Fast 106-MHz (23 mA/ch), VDSL (19.5 mA/ch), ADSL2+ (14.5 mA/ch), and two line-termination modes (<7 mA/ch).
Its design integrates low-output-impedance drivers (<2 Ω per terminal), configurable external series resistors (e.g., 47.5 Ω) for 100-Ω line matching, and an IREF pin supporting external resistor-based quiescent current tuning. The device maintains stable common-mode output voltage (6.0 V ±0.1 V) and achieves 10600 V/µs slew rate in G.Fast 212-MHz mode while operating from a single 12-V supply (11.4–12.6 V range).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Differential Gain | 11 V/V (fixed, enables precise 1:1 DMT signal amplification without external gain-setting components) |
| Linear Output Current | 80 mA min (supports 8 dBm line power into 100-Ω load up to 212 MHz in G.Fast mode) |
| MTPR @ 212 MHz | 48 dBc (measured at 8 dBm line power; critical for minimizing inter-carrier interference in high-bandwidth DSL) |
| Supply Voltage Range | 11.4–12.6 V (12-V technology enables high-voltage headroom for wide-swing DSL line driving) |
| Quiescent Current (G.Fast 212) | 39–44.5 mA per channel (programmable via M11/M12 pins; balances linearity vs. power in CO applications) |
| Crosstalk (212 MHz) | 75 dB (channel-to-channel isolation ensures minimal interference between dual-port DSL lines) |
| Slew Rate | 10600 V/µs (enables faithful reproduction of fast-rising DMT symbols in 212-MHz G.Fast profile) |
Pinout & Package
THS6302IRHFR is housed in a 4.00 mm × 5.00 mm, 28-pin VQFN package with exposed thermal pad connected to GND for enhanced thermal dissipation in high-power DSL line cards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IREF (Pin 1) | Bias current reference | External resistor sets total quiescent current for both channels; enables fine-tuning beyond factory bias modes |
| INA+/INA− (Pins 2,3) | Differential input A | 10-kΩ internal input impedance; matched externally to 100 Ω for DSL line interface |
| INB+/INB− (Pins 7,6) | Differential input B | Independent second channel input; identical architecture to Channel A for dual-line CO deployment |
| OUTA+/OUTA− (Pins 27,25) | Differential output A | Low-impedance outputs (<2 Ω); series resistors (e.g., 47.5 Ω) set 100-Ω line termination |
| OUTB+/OUTB− (Pins 10,12) | Differential output B | Second independent output pair; supports simultaneous dual-line DSL transmission |
| M11/M12 (Pins 28,26) | Channel A bias control | Two-pin three-level interface (0/Z/1) selects one of nine operational modes for Channel A |
| M21/M22 (Pins 9,11) | Channel B bias control | Independent mode control for Channel B; enables asymmetric configuration (e.g., A=212 MHz, B=VDSL) |
| VS (Pins 16,18,19,20) | Positive supply | Four dedicated supply pins reduce IR drop and improve PSRR in high-current DSL operation |
| GND (Pins 4,5,17,21) | Ground | Four ground connections + thermal pad ensure low-impedance return path and thermal stability |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar DSL line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS6301IRHFT | Single-port variant; identical bias modes, gain, and MTPR specs but half the channel count and lower thermal load | Targeted for CPE (customer premises) DSL modems rather than CO line cards; lacks dual-port synchronization capability | Select THS6301IRHFT when designing compact, cost-sensitive CPE equipment with single-line requirements |
| LMH6401IRMTR | DC-coupled RF driver with 9 GHz bandwidth; no integrated DSL bias modes or MTPR optimization; requires external gain/offset control | Used in microwave backhaul and optical IF amplification - not qualified for DSL spectral mask compliance or transformer-coupled line driving | Choose LMH6401IRMTR only for non-DSL wideband analog signal paths where programmable DSL-specific biasing is unnecessary |
Compared with THS6302IRHFR, THS6301IRHFT offers identical per-channel performance in a smaller footprint for CPE use, while LMH6401IRMTR provides raw RF bandwidth without DSL-specific linearity or power-efficiency optimizations - making THS6302IRHFR the only solution qualified for G.Fast 212-MHz CO deployment with integrated bias control and MTPR compliance.

FAQ
What DSL profiles does the THS6302IRHFR officially support?
The THS6302IRHFR is explicitly designed and characterized for G.Fast 106-MHz and 212-MHz profiles, G.mgFast 424-MHz compatibility, VDSL-30a and VDSL-17a, and ADSL2+. Its datasheet specifies MTPR, slew rate, and gain flatness across all these profiles - confirming full functional support without derating or external compensation.
How does the THS6302IRHFR achieve low power in line-termination mode?
The THS6302IRHFR enters low-power line-termination mode (bias Z0) by configuring M11/M12 or M21/M22 pins to Z/0, reducing quiescent current to 6.3 mA per channel while maintaining 100-Ω output impedance via internal circuitry. This avoids signal distortion on shared copper pairs during idle periods - a key requirement for multi-drop DSLAM architectures.
Can the THS6302IRHFR drive a 100-Ω line directly without external components?
No - the THS6302IRHFR requires external 47.5-Ω series resistors on each output (OUTA+/OUTA−, OUTB+/OUTB−) to achieve precise 100-Ω differential line termination. Its internal output impedance is <2 Ω; the external resistors set the final characteristic impedance and dampen reflections critical for DSL signal integrity above 100 MHz.
What is the role of the IREF pin on the THS6302IRHFR?
The IREF pin on the THS6302IRHFR accepts an external resistor to fine-tune total quiescent current across both channels. With a nominal 75-kΩ resistor, it sets typical bias currents per mode (e.g., 39 mA/ch in G.Fast 212-MHz). Increasing resistance lowers current (reducing power/heat); decreasing raises current (improving linearity at cost of thermal load).
Is the THS6302IRHFR pin-compatible with any other TI DSL drivers?
Yes - the THS6302IRHFR shares identical VQFN-28 packaging, pinout, and bias control interface with the THS6301IRHFT (single-port version). This enables drop-in replacement in layouts where only one channel is used, simplifying design reuse between CPE and CO platforms while preserving layout, thermal, and decoupling design.
