SATA “Y” Bridge IP Core

The IntelliProp IPP-SA111A-BR SATA Y Bridge IP Core is a production-hardened, high-availability storage solution engineered to allow two discrete SATA host controllers to safely share a single, standard SATA storage target (SSD or HDD). Operating entirely within the hardware logic fabric, this core acts as an intelligent, low-latency arbiter, providing the foundational logic required to build mission-critical, redundant storage architectures.

In high-reliability systems, processor failure or path disruption can cause catastrophic data loss. The SATA Y Bridge resolves this by establishing an active hardware-level gateway that dynamically arbitrates commands from a primary and a secondary host down to a single device interface. By managing the protocol handshakes and switching logic in pure hardware, the core ensures near-zero latency propagation and instantaneous failover paths without relying on complex, slow software intervention.

Fully compliant with industry-standard Serial ATA specifications, the IPP-SA111A-BR eliminates the design friction of building multi-host multiplexing logic from scratch. Its clean, fully synchronous RTL architecture is optimized for predictable timing closure, making it an ideal choice for high-assurance defense applications, aerospace monitoring systems, and enterprise data center infrastructure requiring uninterrupted uptime.

Features

• Dual-Host Arbitration: High-performance hardware logic engineered to manage safe, concurrent connection points from two independent SATA hosts to a single target drive.
• Hardware-Managed Failover: Internal state machines automate path selection and host switching to ensure rapid, deterministic failover without host processor overhead.
• Deterministic Throughput: Maintains line-rate serial storage speeds across the active bridge path with minimal, sub-microsecond propagation delay.
• Clean Protocol Isolation: Features decoupled internal buffering to isolate signaling paths, preventing a failure on one host path from compromising the entire storage network.
• Full Speed Interoperability: Native hardware alignment supporting standard SATA 1.5 Gb/s, 3.0 Gb/s, and high-speed 6.0 Gb/s link rates across all active ports.
• Flexible PHY Integration: Integrates smoothly with a wide range of industry-standard transceiver layers via standard SerDes or PIPE configurations.
• Production-Proven Maturity: Extensively validated using a comprehensive, coverage-driven verification methodology in pseudo-random simulation environments.
• Synchronous Design Layout: Clean, fully synthesizable RTL structure tailored for quick placement, routing, and predictable timing closure across major FPGA and ASIC families.
