# Industrial Specification: Protocol PHY Chip

## 1. Technical Definition
A semiconductor component that implements the physical layer (PHY) of a communication protocol within an interface module.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-125°C ambient temperature, 1.8-3.3V supply voltage, 0-1.5V differential signal amplitude**. Failure boundary: **Junction temperature exceeding 150°C, supply voltage deviation beyond ±10% of nominal, signal amplitude below 100mV differential**, Mechanism: **Thermal runaway due to excessive power dissipation (P = I²R + CV²f), dielectric breakdown at 5MV/m electric field strength, electromigration at current density &gt; 1×10⁶ A/cm²**.
