56G-LR Pam4 SerDes PHY

Overview

The 56G Long-Reach (LR) SerDes PHY provides exceptional performance with best-in-class power and area, making it ideal for machine learning (ML) and 5G infrastructure applications.

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 Features

  • Supports Ethernet, FC, CPRI, and eCPRI protocols
  • Compliant to IEEE 802.3ck and OIF standard electrical specifications
  • Supports 56Gbps PAM4 and 28G, 10G, and sub-10Gbps NRZ data rates
  • Unique firmware-controlled adaptive power design provides optimal power and performance tradeoffs and more efficient system designs based on platform requirements
  • Continuous calibration and adaption provide robust performance across process, voltage, and temperature
  • Supports industrial temperature range -40°C – 125°C

Benefits

  • High Flexibility: Multi-rate support provides backward compatibility with legacy equipment operating at lower speeds
  • Robust Performance: ADC/DSP-based receiver architecture provides superior data recovery for lossy and noisy channels
  • Ease of Use: Fully autonomous startup and adaptation, SNR monitoring, as well as integrated BIST capable of producing and checking PRBS
