Brite Semiconductor Releases PCIe 4.0 PHY IP

Shanghai, China — August 14, 2025 — Brite Semiconductor (Shanghai) Co., Ltd. (BriteSemi, 688691), a leading provider of custom ASIC and IP solutions, today announced the launch of PCIe 4.0 PHY IP based on 28HKC+ 0.9V/1.8V platform‌. The PHY IP complies with PCIe 4.0 specifications, supports PIPE 4.4.1/5.2 interface and data transmission rates ranging from 2.5Gbps to 16Gbps, fully covering PCIe Gen4.0/3.0/2.0/1.0 standards, and is compatible with other protocols, such as Rapid IO, JESD204B/C, USB3.2/3.1/3.0, and 10GBASE-R/KR‌. With its outstanding performance and low power consumption, the PCIe 4.0 IP can be widely used in various application scenarios such as custom design based on RISC-V processor, AI & machine learning, HPC, edge computing, 5G, communication & network equipment, intelligent image processing, AR/VR, and ADAS & intelligent cockpit, etc., meeting the high-performance requirements of high-speed data transmission ‌and low-power design.

The PCIe 4.0 IP demonstrates flexible configuration capabilities across different applications, achieved through parallel or cascaded dual PLL‌. Its universal high-speed LC-PLL clock generation module supports 8+ channels according to jitter requirements, enabling versatile macro configurations such as 1x, 2x, 4x and 8x. Additionally, independent PLL in data lanes enhances power efficiency and enables their separate configuration across different protocols. The PCIe 4.0 IP performs continuous clock, slicer and analog front-end (AFE) offset calibration during data transmission and reception without interruption, capable of handling large frequency offsets. It supports configuration for different data widths, such as 8-bit, 16-bit, 20-bit, 32-bit and 40-bit, and supports high coverage, full-speed Built-In Self-Test (BIST) and loopback testing. These features indicate that the IP is suitable for diverse application scenarios, delivering ‌efficient, flexible, and accurate clock and data calibration‌ to ensure ‌reliability and stability during data transmission‌.

BriteSemi’s PCIe 4.0 IP has been successfully silicon-proven, passed all of the function and performance tests, with all parameters meeting target specifications, and released for customer mass production.
