Quad Port Bypass Circuit

forFibreChannelArbitratedLoops

DataSheet

Description

Features

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.

• 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)

A PBC consists of multiple 2:1 multiplexers daisy

chained together. Each port has two modes ofoperation:

“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. For example, data goes from

the HDMP-0440’s TO_NODE[n]± differential output

pins to the Disk Drive Transceiver IC’s (e.g. an HDMP-

1636A) Rx differential input pins. Data from the Disk

Drive Transceiver IC’s Tx differential outputs goes to

the HDMP-0440’s FM_NODE[n]± differential input

pins. Figure 2 shows connection diagrams for disk

drive array applications. When the “disk bypassed”

mode is selected, the disk drive is either absent or non-

functional and the loop bypasses the hard disk.

• 0.5 W typical power at V = 3.3 V

• 44 Pin, 10 mm, low-cost plastic QFP package

Applications

• RAID, JBOD, BTS cabinets

• Two 2:1 muxes

• Two 1:2 buffers

• 1 ≥ N Gigabit serial buffer

• N ≥ 1 Gigabit serial mux

The “disk bypassed” mode is enabled by pulling the

BYPASS[n]- pin low. Leave BYPASS[n]- floating to

enable the “disk in loop” mode. HDMP-0440s may be

cascaded with other members of the HDMP-04XX/

HDMP-05XX family through the appropriate

FM_NODE[n]± and TO_NODE[n]± pins to

accommodate any number of hard disks (see Figure

3). The unused cells in the HDMP-0440 maybe bypassed

by using pulldown resistors on the BYPASS[n]- pins

for these cells.

HDMP-0440

An HDMP-0440 may also be configured as five 1:1

buffers, as two 2:1 multiplexers or as two 1:2 buffers.

CAUTION: As with a ll semiconductor ICs, it is a dvised tha t norma l sta tic preca utionsb be ta ken in

the ha ndling a nd a ssembly of this component to prevent da ma ge a nd/ or degra da tion which ma y be

induced by electrosta tic discha rge (ESD).
