[Domestic AI Server] Fully Domestic PCIe 5.0 Switch Board, Replaces Broadcom 89104/89144, Supports Hygon, Loongson, and Other Platforms

1. Controller Chip‌

Uses domestic TL63104 controller chip, supports PCIe transfer rates of 2.5GT/s, 5GT/s, 8GT/s, 16GT/s, 32GT/s, and supports 96+8 lanes. Supports 6 x16 groups and 1 x8 group, with each group supporting 1 to 8 ports. x16 groups support x16, x8, x4, x2 ports; x8 groups support x8, x4, x2, x1 ports.
Basic Mode: Extends PCIe interfaces and supports multi-level expansion, as shown in the figure below.

NT Mode: Interconnects multiple PCIe domains, supporting NTB and DMA features, as shown in the figure below.
‌P2P Mode: Supports data transfer between any DPs, effectively increasing transfer bandwidth and reducing transfer latency.
Supports non-blocking crossbar architecture.
Integrates SM2/SM3/SM4 encryption engines to ensure data transmission security, meeting domestic replacement requirements.
Supports standard hot-plug and surprise hot-plug.

2. Expansion Interfaces‌

Upstream Bus Interface: PCIe Gen5 x16, gold finger connector.
Downstream Interfaces and Connectors:
