Overview

Hyperscale computing continues to be the main driver for very high-speed SerDes, and 112G/56G is a key enabler for cloud data center and optical networking applications. 56G connectivity is particularly important for 5G infrastructure deployment, both in baseband and remote radio head systems. 

The 56G-LR SerDes PHY IP supports PAM4 and NRZ signaling and data rates from 1Gbps to 56Gbps. This silicon-proven IP incorporates industry-leading analog-to-digital converter (ADC), clock-data-recovery (CDR) and digital signal process (DSP) technology that enables the support of greater than 45dB channel. 

Key Benefits
