The Glasswing SerDes family is a set of programmable IPs designed and optimized for in-package applications. Glasswing provides high system bandwidth with low power consumption through the use of CNRZ-5-DR-EE Chord signaling and a forwarded clock architecture. Deploy Glasswing IP in multiple instances to provide efficient extended interfaces
Technology
- GlobalFoundries® 12LP process
- 0.9V and 1.2V analog supplies
- 0.8V digital supply
- Junction temperature -40 to +110 °C
- Standard flip chip technology with 150 μm bump pitch
- Tile-able layout to support high IO density
CNRZ coding
- Transmits 5 bits on 6 correlated wires:
- Balanced code leads to low SSO noise at transmitter
- Employs a reference-less receiver that is resilient to common-mode noise
- Uses a receiver that has five comparators and no decoder
- Link has excellent signal integrity properties:
- NRZ-like ISI properties
- Scalable to much higher speeds and harder
- channels
- NRZ-like EMI performance
