The multi-channel Synopsys PHY IP for PCI Express® 4.0 includes Synopsys’ high-speed, high-performance transceiver to meet today’s applications’ demands for higher bandwidth. The PHY’s cost-effective solution meets the needs of today’s high-speed chip-to-chip, board-to-board, and backplane interfaces while being extremely low in power and area.
Using leading-edge design, analysis, simulation, and measurement techniques, Synopsys delivers exceptional signal integrity and jitter performance that exceeds the PCI Express standard’s electrical specifications. The high-margin, robust PHY architecture tolerates process, voltage and temperature (PVT) manufacturing variations and is implemented with standard CMOS digital process technologies.
The multi-tap transmitter and receiver equalizers, along with the advanced built-in diagnostics and ATE test vectors, enable customers to control, monitor
and test for signal integrity without the need for expensive test equipment. This provides on-chip visibility into actual link and channel performance to quickly improve signal integrity. This capability reduces both product development cycles and the need for costly field support.
PCIe 4.0 PHY in
Overview
Key Features
