Glasswing IP Family: GW28-125-USR SerDes 125Gbps Throughput


418 KB PDF

The Glasswing SerDes family is a programmable IP designed and optimized for in-package applications. Glasswing provides high system bandwidth with low power consumption through the use of 5b6w ChordTM signaling and employs a forwarded clock architecture. The Glasswing IP may be deployed in multiple instances to provide efFicient extended interfaces.

The GW28-125-USR SerDes is a hard IP SerDes solution that provides a high throughput for short reach interposer and multi-chip-module applications such as chip-to-chip, processor or switch to memory, and in- package interfaces. Typical supported applications will deliver 25GBaud over channels of 5mm to 25mm with insertion losses in the range 3dB to 6dB at Nyquist.

The GW28-125-USR achieves low power through coding, efFicient circuitry, simple clocking and equalization schemes.
