PHY-nomenal Success with Proven Track Record

Phison was the first in the world to ship a PCIe Gen4 SSD in 2019, and an excellent PCIe Gen4 SerDes PHY was a key factor to making it happen.

Jitter Tolerance

Phison's PHYs test well above the PCI-SIG specification in their RX jitter tolerance. Specifically, the solution inside PS5016-E16 that fueled Phison's PCIe Gen4 breakthrough was proven with over 10X of margin over the specification.

Compliance Testing

PS5016-E16 was powered by Phison's PCIe Gen4 SerDes PHY and established as the industry standard for AMD PCIe Gen4 platform compliance. With all subsequent generations of PHY IPs, Phison continues to deliver with the same excellence in system front-end compliance.
