草榴社区

The 草榴社区 224G Ethernet PHY IP meets the growing high bandwidth and low latency needs of high-performance data center applications. Using leading-edge design, analysis, simulation, and measurement techniques, the 草榴社区 224G Ethernet PHY delivers exceptional signal integrity and jitter performance that exceeds the IEEE 802.3 and OIF standards electrical specifications. The area efficient PHY provides additional margin for channel loss and demonstrates zero post-FEC BER.

The PHY supports the Pulse-Amplitude Modulation 4-Level (PAM-4) and Non-Return-to-Zero (NRZ) signaling to deliver up to 1.6T Ethernet. The configurable transmitter and advanced DSP-based receiver with analog-to-digital converter (ADC) enable designers to control and optimize signal integrity and performance. The CCA algorithm provides a robust performance across voltage and temperature variations. The low jitter PLLs and multi-loop clock and data recovery circuits provide robust timing recovery and better jitter performance, while the embedded bit error rate (BER) tester and internal eye monitor provide on-chip testability and visibility into channel performance.
