THS6302IRHFR

Instrumentation, Op Amps, Buffer Amps Overview

The THS6302IRHFR is a dual-port, current-feedback differential line driver designed for G.Fast and xDSL systems. It supports G.Fast profiles up to 212 MHz and legacy VDSL/ADSL2+. Key electrical parameters include a supply voltage range of 11.4 V to 12.6 V, an internal fixed gain of 11 V/V, and a linear output current of at least 80 mA in high-power modes. The device operates within a temperature range of -40°C to +85°C and features adjustable quiescent current via an external resistor.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Supports G.Fast 212-MHz profiles with excellent Multitone Power Ratio (MTPR) performance
• Features nine selectable bias modes for optimized power efficiency across various DSL standards
• Includes two line-termination modes to maintain impedance matching during low-power states
• Allows quiescent current adjustment through an external IREF pin

Instrumentation, Op Amps, Buffer Amps Applications

• G.Fast digital subscriber line systems
• Central Office (CO) DSL applications
• G.mgFast compatible line drivers
• Legacy ADSL2+ and VDSL line drivers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'RHFR' against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required thermal management solutions for the VQFN package. Confirm that the design meets the absolute maximum ratings for supply voltage and input signals to prevent permanent damage.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for Central Office applications requiring dual-channel drive capabilities. Compare against the single-port THS6301 if only one channel is needed. Consider the available bias modes to balance power consumption against bandwidth requirements for specific DSL profiles such as G.Fast 106-MHz or 212-MHz.

Instrumentation, Op Amps, Buffer Amps Part Context

The THS6302 belongs to Texas Instruments' portfolio of high-speed amplifiers and line drivers. It is part of the THS63xx series, specifically engineered for broadband communication interfaces. The device utilizes a 28-pin VQFN package to provide a compact solution for dense PCB layouts in telecommunications equipment.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The THS6301 is a single-port variant suitable for Customer-Premises Equipment (CPE). Verify functional equivalence if replacing with other members of the THS63xx family.
