Key Advantages of H-PHY™ Architecture

A current-domain PHY architecture designed for ultra-low energy, high bandwidth, compact silicon footprint, and robust signal integrity.

01

Ultra-Low Energy

H-PHY is architected to reduce CV2 switching energy through ultra-low-swing signaling while mitigating the impact of interconnect capacitance and crosstalk in short-reach links.

02

Technology-Scalable High Bandwidth Architecture

Designed to benefit from advanced process technologies while supporting higher bandwidth and energy-efficient operation.

03

NRZ/PAM-Optimized Architecture

Designed for bidirectional NRZ and multi-level PAM communication, featuring differential PAM signaling and DC-balanced encoding to deliver scalable bandwidth, ultra-low energy, reduced SSN, and improved PDN integrity.

04

Compact Silicon Footprint

Current-domain signaling and an RX-centric architecture reduce PHY complexity and enable a compact per-channel implementation.

05

Level-Shifter-Free Architecture

Designed to operate within the core-voltage domain without dedicated TX or RX level shifters, reducing power, area, and latency overhead.

06

Minimal or No Equalization Requirement

For high-quality short-reach interconnects, H-PHY is designed to operate with minimal or no equalization, reducing the power, area, and latency overhead associated with conventional equalizers.
