# Industrial Specification: PHY Transceiver

## 1. Technical Definition
A hardware component that implements the physical layer (PHY) functions for data transmission and reception in communication systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-125°C ambient temperature, 1.8-3.3V supply voltage, 0-10 Gbps data rate**. Failure boundary: **Junction temperature exceeding 150°C, supply voltage deviation beyond ±10% of nominal, signal-to-noise ratio dropping below 15 dB**, Mechanism: **Thermal runaway due to excessive power dissipation (P = I²R), dielectric breakdown in CMOS transistors at overvoltage, intersymbol interference from channel dispersion**.
