HDMP-0450 - Quad Port Bypass Circuit

Download the HDMP-0450 datasheet PDF. This datasheet also covers the HDMP-0450_Hewlett variant, as both devices belong to the same quad port bypass circuit family and are provided as variant models within a single manufacturer datasheet.

Description

The HDMP-0450 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.

Features

  • Supports 1.0625 GBd Fibre Channel operation.
  • Supports 1.25 GBd Gigabit Ethernet (GE) operation.
  • Quad PBC in one package.
  • Signal detect on FM_NODE[0] input.
  • Equalizers on all inputs.
  • High speed LVPECL I/O.
  • Buffered Line Logic (BLL) outputs (no external bias resistors required).
  • 0.5 W typical power at VCC = 3.3 V.
  • 44 Pin, 10 mm, low-cost plastic QFP package.

www.DataSheet4U.com Agilent HDMP-0450 Quad Port Bypass Circuit for Fibre Channel Arbitrated Loops Data Sheet Description The HDMP-0450 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-0450, hard disks may be pulled out or swapped while other disks in the array are available to the system. A PBC consists of multiple 2:1 multiplexers daisy chained together. Each port has two modes of operation: “disk in loop” and “disk bypassed.” When the “disk in loop” mode is selected, the loop goes into and out of the disk drive at that port.
