Backplane & Line Card Connectivity
Bald Eagle Retimer
Credo is at the forefront of 400G/800G backplane and line card connectivity. Credo's product offering includes: Retimers, Gearboxes and MACsec devices. The family supports 56G per lane connectivity and PAM4/NRZ signaling for 12.8Tbps platforms. These scale up to 112G per lane for next generation 800G port connectivity solutions to support 25.6Tbps platforms.
Bald Eagle Supports 56G PAM4 and 28G NRZ
Credo is a leading provider of high performance/low power semiconductor solutions for the data center, enterprise networking, and high-performance computing markets. Our innovative Serializer-Deserializer (SerDes) technology delivers the bandwidth, scalability and end-to-end signal integrity needed to meet the demands of advanced networks up to 800G with single-lane 28G, 56G, or 112G connectivity.
Credo’s purpose-built approach to SerDes design enables our products to be built on mature process technology, providing our customers with a competitive edge.
The CRT502XX family is suitable for both backplane and front panel applications including cloud-scale switches, high-density routing platforms, and advanced server NIC cards.
Key Features
- Multi-channel bidirectional retimers for 10 - 56Gbps
- Superior random jitter performance
- 35dB reach at 56Gbps
- CEI-56G-VSR/MR/LR-PAM4 compliant
- CEI-28G-LR and CEI-28G-VSR/SR/MR compliant
- TX equalization with programmable main, pre, and post-cursor
- Fully adaptive and programmable RX equalization with CTLE, FFE, and DFE
- Auto negotiation between the link partners on both sides of the retimer (IEEE 802.3 clause 73)
- KR back-channel training (IEEE 802.3 clause 72,92,93,136)
- Input/output polarity switch control
- Register control via I2C or standard MDIO interface
- Built in diagnostic features including PRBS generator and checker, PRBS FEC Analyzer, internal eye monitor and analog test point
