HDMP-0452 - Quad Port Bypass Circuit

Download the HDMP-0452 datasheet PDF. This datasheet also covers the HDMP-0452_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-0452 is a Quad Port Bypass Circuit (PBC) with a Clock and Data Recovery (CDR) circuit included.

This device minimizes part count, cost and jitter accumulation while repeating incoming signals.

Features

  • Supports 1.0625 GBd fibre channel operation.
  • Supports 1.25 GBd Gigabit Ethernet (GE) operation.
  • Quad PBC/CDR in one package.
  • CDR location determined by choice of cable input/output.
  • Valid amplitude detection on FM_NODE[0] input.
  • Equalizers on all inputs.
  • High speed LVPECL I/O.
  • Buffered Line Logic (BLL) outputs (no external bias resistors required).
  • 0.66 W typical power at VCC = 3.3 V.
  • 44 pin, 10 mm, low co.

www.DataSheet4U.com Agilent HDMP-0452 Quad Port Bypass Circuit with CDR for Fibre Channel Arbitrated Loops Data Sheet Description The HDMP-0452 is a Quad Port Bypass Circuit (PBC) with a Clock and Data Recovery (CDR) circuit included. This device minimizes part count, cost and jitter accumulation while repeating incoming signals. 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. A Port Bypass Circuit (PBC) consists of multiple 2:1 multiplexers daisy chained along with a CDR. Each port has two modes of operation: “disk in loop” and “disk bypassed”.
