PCIe 4.0

OVERVIEW

MSquare's PCI Express 4.0 PHY IP includes a high-speed, highly-efficient, and cost-effective transceiver to turbocharge today's high-performance and high-bandwidth applications such as data centers, automotive, enterprise computing, and high-performance embedded systems.


The PCIe IP boasts a low power consumption and compact silicon footprint. Its robust PHY architecture tolerates process, voltage, and temperature (PVT) variations. This IP integrates high-speed mixed-signal circuits to support PCIe 4.0 traffic at 16Gbps. It is backward compatible with PCIe 3.1 data rates at 8.0Gbps, PCIe 2.1 at 5.0Gbps, and PCIe 1.1 at 2.5Gbps. The multi-tab transceiver design, accompanied by a robust BIST, an embedded bit error rate (BER) tester, and an internal eye monitor, enables designers to control, test, and monitor signal integrity without the need for expensive test equipment.
