Description
The HDMP-0440 is a Quad Port Bypass Circuit (PBC), which provides a low-cost, low-power physical-layer solution for Fibre Channel Arbitrated Loop (FC-AL) disk array configurations. By using a PBC such as the HDMP-0440, hard disks may be pulled out or swapped while other disks in the array are available to the system.

FEATUREs
• Supports 1.0625 GBd Fibre Channel operation
• Supports 1.25 GBd Gigabit Ethernet (GE) operation
• Quad PBC in one package
• Equalizers on all inputs
• High-speed LVPECL I/O
• Buffered Line Logic (BLL) outputs (no external bias resistors required)
