Marvell Switch Design

Marvell Switch Design Services


Marvell Ethernet switches, such as the Prestera and Teralynx families, power high-performance networking for data centers, automotive, and industrial applications, offering scalable, low-latency solutions with up to 64x800GbE ports and 51.2 Tbps throughput. At A2e Technologies, we specialize in designing these complex switches, tackling challenges like high-speed signal integrity, low-jitter PTP synchronization, and advanced security features (e.g., MACsec, DPI). Our expertise in FPGA, mixed-signal design, and embedded software ensures reliable, optimized Marvell switch solutions tailored to your demanding networking needs.

Marvell Switch Design Details:

  • Large multiport switches handle high-speed interfaces like 1/2.5/5/10/25/50/800 Gbps SerDes (Serializer/Deserializer) for ports like XFI, SGMII, or PCIe Gen 3.0. Maintaining signal integrity across dozens of ports (e.g., 64x800GbE in Teralynx 10) is challenging due to crosstalk, impedance mismatches, reflections, and EMI, which can introduce jitter critical for PTP.
  • Implementing PTP (IEEE 1588) with sub-20ns jitter, as A2e achieves, is critical for applications like 5G, automotive ADAS, and industrial IoT. Large switches must distribute precise clocks across multiple ports while minimizing jitter from clock sources, PLLs, and network delays.
  • Supporting high port counts (e.g., 48x1/2.5GbE in Prestera 98DX35xx or 64x800GbE in Teralynx 10) requires managing data throughput (up to 51.2 Tbps) without compromising latency or power efficiency. This is complex in large switches with diverse port speeds (10/100/1000BASE-T, 2.5/5/10/25/50G).
  • Large switches consume significant power (e.g., Teralynx 10 at 1W per 100Gbps), and high port counts increase thermal loads, especially in compact, aerospace or automotive environments.
  • Large switches require robust security features (e.g., 256-bit MACsec, Trusted Boot, DPI) to protect against cyber threats, especially in automotive and data center applications.
  • TSN features (e.g., IEEE 802.1Qci, Qbu) in Marvell switches (e.g., 88EA6352, DX1500) require deterministic latency for industrial and automotive applications, complicating switch design.
  • Validating large multiport switches for performance, jitter, and compliance (e.g., IEEE 802.3, ISO 26262) requires advanced test setups and equipment.
