The multi-lane DesignWare® Multi-Protocol 25G PHY IP is part of Synopsys’ high-performance multi-rate transceiver portfolio for high-end networking and cloud computing applications. The PHY is small in area and provides a low active and standby power solution that supports multiple electrical standards, including PCI Express (PCIe) 4.0, 25G and 100G Ethernet, Cache Coherent Interconnect for Accelerators (CCIX), SATA and other industry-standard interconnect protocols. Using leading-edge design, analysis, simulation, and measurement techniques, the multi-protocol 25G PHY delivers signal integrity and jitter performance that exceeds the standards’ electrical specifications.
The configurable transmitter and receiver equalizers along with Continuous Calibration and Adaptation (CCA) enable designers to control and optimize signal integrity and performance across voltage and temperature variations. The PHY provides advanced power management features for both standby and active power. The embedded bit error rate tester (BERT) and internal eye monitor provide on-chip testability and visibility into channel performance. The PHY integrates seamlessly with the DesignWare Physical Coding Sublayers (PCS) and digital controllers/Media Access Controllers (MACs) to reduce design time and to help designers achieve first-pass silicon success.
