THS6222YS

Overview

The THS6222YS is a silicon-germanium (SiGe) die intended for wafer-level integration into custom packages. It functions as a differential high-speed power line communications (HPLC) line driver with an integrated common-mode buffer. The device operates on a supply voltage range of 8V to 32V and supports multiple adjustable bias modes, including full-bias, mid-bias, low-bias, and shutdown states. Key electrical characteristics include a large-signal bandwidth of 195MHz at 16VPP output swing and a slew rate of 5500V/µs. It provides an output current capability of 338mA and features integrated overtemperature protection.

Feature Summary

• Utilizes a proprietary high-speed silicon-germanium process for broadband HPLC applications requiring high linearity.
• Features an integrated midsupply common-mode buffer that eliminates the need for external components.
• Supports adjustable power consumption through selectable bias modes and an IADJ pin for variable current control.
• Includes built-in overtemperature protection to ensure operational reliability under heavy load conditions.

Applications

• SGCC HPLC line drivers compliant with IEEE 1901.1 standards
• Smart meters and data concentrators utilizing PLC technologies
• Power line communications gateways supporting G.hn, PRIME BPL, G3, and ISO 15118 protocols

Procurement Notes

Verify the specific wafer lot and die orientation requirements before integrating the THS6222YS into custom packaging solutions. Confirm that the design environment supports the exposed thermal pad connection to the negative supply rail for optimal thermal performance. Ensure ESD handling procedures meet the specified human body model ratings during assembly.

Selection Notes

Select this component when designing custom ASICs or hybrid modules for high-performance power line communication systems. It is suitable for applications demanding wide dynamic range and minimal distortion while driving heavy line loads. Consider the available bias modes to optimize power efficiency in time division multiplexed environments where receive mode power savings are critical.

Part Context

The THS6222YS represents the bare die version of the Texas Instruments THS6222 family. While packaged versions like the RGT and RHF utilize standard VQFN formats, the YS suffix indicates a wafer sale configuration. This allows system integrators to incorporate the amplifier directly into their own substrate designs, offering flexibility in form factor and interconnect topology for specialized industrial networking hardware.

Replacement Considerations

Publicly confirmed substitute part numbers are not documented for the THS6222YS die variant. Designers seeking equivalent functionality should evaluate the packaged THS6222RGT or THS6222RHF variants, noting that these require different mounting and thermal management approaches compared to direct die attachment.

FAQ

How is the common-mode voltage managed in the THS6222YS?

The device includes an integrated midsupply common-mode buffer. The VCM pin provides the buffered common-mode voltage, which can be decoupled with a capacitor to minimize noise without requiring external buffer circuits.

What is the function of the BIAS-1 and BIAS-2 pins on the die?

These pins control the operating bias mode of the amplifier. By setting logic levels on BIAS-1 and BIAS-2, users can select between full-bias, mid-bias, low-bias, or shutdown modes to balance performance and power consumption.
