HFBR-5103A

100 Mbps ATM, and Fast Ethernet Transceivers in Low Cost 1x9 Package Style

HP => Agilent Technologies 

These transceivers can also be

used for applications which

require different Bit Error Rate

(BER) performance. Figure 6

illustrates the typical trade-off

between link BER and the

receivers input optical power

level.

Transceiver Jitter Performance

The Agilent 1300 nm transceivers

are designed to operate per the

system jitter allocations stated in

Tables E1 of Annexes E of the

FDDI PMD and LCF-PMD

standards.

The Agilent 1300 nm transmitters

will tolerate the worst case input

electrical jitter allowed in these

tables without violating the worst

case output jitter requirements of

Sections 8.1 Active Output

Interface of the FDDI PMD and

LCF-PMD standards.

The Agilent 1300 nm receivers will

tolerate the worst case input

optical jitter allowed in Sections

8.2 Active Input Interface of the

FDDI PMD and LCF-PMD

standards without violating the

worst case output electrical jitter

allowed in the Tables E1 of the

Annexes E.

The jitter specifications stated in

the following 1300 nm transceiver

specification tables are derived

from the values in Tables E1 of

Annexes E. They represent the

worst case jitter contribution that

the transceivers are allowed to

make to the overall system jitter

without violating the Annex E

allocation example. In practice

the typical contribution of the

Agilent transceivers is well below

these maximum allowed amounts.

Recommended Handling Precautions

Agilent recommends that normal

static precautions be taken in the

handling and assembly of these

transceivers to prevent damage

which may be induced by

electrostatic discharge (ESD). The

HFBR-5100 series of transceivers

meet MIL-STD-883C Method

3015.4 Class 2 products.

Care should be used to avoid

shorting the receiver data or signal

detect outputs directly to ground

without proper current limiting

impedance.
