Package and Handling Information

Package Information

The receiver is housed in a low-cost, dual-inline package

that is made of high strength, heat resistant, chemically

resistant, and UL 94V-O ame retardant ULTEM® plastic

(UL File #E121562). The receivers (sux Z, TZ) are easily

identied by the dark grey color connector port. A metal

port option is also available (sux MZ). The metal port op-

tion components have an internal electrical connection

between the metal port and the four grounding pins, as

shown in the package outline drawing. Signal ground is

separate from the four grounding pins to give exibility in

connecting the port to signal or chassis ground. The pack-

age is designed for auto-insertion and wave soldering so

it is ideal for high volume production applications.

Handling and Design Information

Each part is delivered with a protective port cap or a plug

covering the optics. These caps/plugs will vary by port

style. When soldering, it is advisable to leave the protec-

tive cap on the unit to keep the optics clean. Good system

performance requires clean port optics and cable ferrules

to avoid obstructing the optical path. Clean compressed

air often is sucient to remove particles of dirt; methanol

on a cotton swab also works well.

AFBR-24x9xZ Low-Cost 50 MBd Receiver

Description

The AFBR-24x9xZ ber optic receiver is designed to oper-

ate with the Avago Technologies HFBR-14xxZ ber optic

transmitters and multimode glass ber cable. Consistent

coupling into the receiver is assured by the optical system

with lens. The receiver output is a digital CMOS/TTL signal.

The AFBR-24x9xZ receiver contains an IC with integrated

photodiode which directly converts the incoming opti-

cal signal to a digital output signal without the requisite

for additional external circuitry. Because of its integrated

design, the receiver has very high EMC resistance. A wide

receiver dynamic range and high sensitivity over tempera-

ture is achievable. The data rate typically goes from 100

kBd to 50 MBd. A monitor (RSSI) output, which delivers an

output current proportional to the average incoming light

power, is available.

For an almost noise-free RSSI-signal smoothing compo-

nents are recommended. A capacitor in parallel to the

resistor on the RSSI output reduces potential high fre-

quency signal parts. The use of a single 100 nF capacitor

for signal smoothing is sucient in most common appli-

cations, as shown in the Recommended Receiver Circuitry

section on page 4. If this RSSI function is not required, the

output pin can be left oating. The RSSI-signal is derived

from internal controlling loops; therefore, the typical time

constant of pure RSSI output current without an external

lter can be up to 1 ms. This time constant also depends

on the actual average incoming light power.

2. In recommended receiver circuit, with an optical signal from the recommended transmitter circuit, transmitted via 62.5/125 µm MM ber.

3. Condition for sensitivity limit: Total Jitter ≤ 0.6 UI (unit intervals).

4. Veried with a PRBS7 signal with mark ratio = ½ running at 40 MBd.

5. Veried with a PRBS7 signal with mark ratio = ½ running at 50 MBd.

6. Veried with a jitter-free Manchester coded pseudo random sequence running at 20 MBd (~10 Mbit/s) as optical input signal.

7. The device does not support DC operation. Hence any static low or high at the input will cause an undened output signal.

8. The RSSI current output has been veried with an external resistor RRSSI=2 kΩ

9. The PWD is valid for the receiver only, assuming an ideal 50% duty cycle optical input signal. PWD = PWOUT-AVG - PWIN-AVG

Operation with unbalanced pattern (mark ratio ≠ 1/2 or DC ≠ 50%) will cause a higher PWD than what is specied in this table.

Notes

1. Pins 1, 4, 5 and 8 are connected together internally. The metal port option components (sux MZ) have an internal electrical connection between

the metal port and the four grounding pins

2. The data output provides an inverted signal, thus an electrical low in case of light on and vice versa.

Note:

To provide a suitable monitoring voltage , choose the value of RRSSI according to the particular optical power situation. For the characterization of the

responsivity, 2 kΩ was used. The lower the power, the higher the resistor value should be. Do not, however, override the max. limit of VRSSI.
