Description
The HDMP-0480 is an Octal Cell Port Bypass Circuit (PBC). This device minimizes part count, cost and jitter accumulation. Port Bypass Circuits are used in hard disk arrays constructed in Fibre Channel Arbitrated Loop (FC-AL) configurations. By using Port Bypass Circuits, 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
• Octal cell PBC in one package
• Valid amplitude detection on FM_NODE[7] input
• Equalizers on all inputs
• High speed LVPECL I/O
• Buffered Line Logic (BLL) outputs (no external bias resistors required)
• 0.76 W typical power at Vcc=3.3V
• 64 Pin, 10 mm, low cost plastic QFP package

Applications
• RAID, JBOD, BTS cabinets
• Four 2:1 muxes
• Four 1:2 buffers
• 1 = > N gigabit serial buffer
• N = > 1 gigabit serial mux
