EDR 51xx Series
Access PIN-TIA Receivers for 155 Mb/s and 622 Mb/s
Description
The EDR 51xx Series incorporates a 75 µm InGaAs PIN photodetector
coupled with a low cost BiCMOS transimpedance amplifier (TIA)
designed to operate at 155 Mb/s (EDR 512x) or 622 Mb/s (EDR 515x).
The PIN transduces optical power into current with high efficiency. The
TIA converts the current signal into a voltage signal with a very low
input noise current contribution. The EDR 512x TIA also integrates an
automatic gain control (AGC) circuit which decreases the light to
voltage conversion factor when the average incident optical power is
relatively high.
The EDR 51xx Series are assembled in rugged coaxial packages. They
are available with a connector receptacle or as a single mode fiber
pigtail. Standard choices for connector receptacles are LC, SC and FC. In
addition, the EDR 51xx Series are available in several standard pin-out
configurations. The EDR 51xB is the simplest configuration and
provides a single ended output. The EDR 51xC provides access to the
photodiode current for those customers who need to design an alarm
circuit. The EDR 51xD provides a differential output for higher gain
performance without sacrifice to sensitivity and bandwidth.

Performance Highlights
The EDR 51x Series offer a sensitivity of better than -36 dBm (EDR 512x) or
-30 dBm (EDR 515x) with appropriate filtering and a minimum overload of
0 dBm (EDR 512x) or -7 dBm (EDR 515x). This large dynamic range makes
these products ideal for both long and short range applications. A time
constant of 4 milliseconds makes the AGC circuit of the EDR 512x models
very stable, even during reception of the longest streams of high or low
logic levels. The EDR 51x Series operate over -40 to +85°C.
The EDR 51x Series provide significant benefits over hybrid designs and
14-pin receivers. Integration of the TIA with the PIN detector onto the TO-46
header reduces parasitic capacitances and lead inductances. The TO-52 cap
hermetically seals the hybrid and provides EMI shielding especially from the
transmitter circuit. These advantages improve sensitivity over designs that
place the amplifier outside the capsule and away from the detector. The
EDR 51x Series, which have four pins, are advantageous over 14-pin receivers
because they require less board space and fewer electrical connections. In
addition, the EDR 51xx Series operate from a single power supply, even in
the pin-out configuration which provides photodiode current monitoring.
The smaller form factor and the need for a single power supply make the
EDR 51x Series a less expensive, high performance alternative to other kinds
of optical receivers.
Typical Applications
The EDR 51xx Series are designed for many applications, including single
mode 155 Mb/s (EDR 512x) and 622 Mb/s (EDR 515x) ATM receivers. The
EDR 51xx Series exceed Long Reach OC-3 (EDR 512x) and OC-12 (EDR
515x) SONET receiver specifications and are ideal for transceiver designs
or board level discrete designs. Applications include receivers for digital
cross connects, digital loop carriers, add/drop multiplexers, optical
network units and switches and routers for LAN and WAN backbones.

External Circuitry
When designing the EDR 51xx Series into an optical receiver, standard
high speed printed circuit board design practices should be observed.
For example, bypassing of the power supply is recommended so as to
reduce noise that appears at the output of the PIN-TIA.
If signal traces are relatively long, use impedance matching techniques
to maximize power transfer from the PIN-TIA to its load: for microstrip
design, assume 70 ohms (EDR 512x) and 60 ohms (EDR 515x) as the
output impedance for the PIN-TIA. Note as well that the output of the
PIN-TIA is DC-coupled. Since most applications require AC-coupled
stages, a high-Q RF chip capacitor should be placed on the output of the
module. To eliminate oscillations, the PIN-TIA should be mounted on a
circuit board with a large, low impedance ground plane. All the PIN-TIA
leads should be made as short as possible in order to reduce excess
inductances. As a general rule, receiver bandwidth requirements need
only be greater than about 1/3 of the bit rate at which they are intended
to operate. A receiver for a 155 Mb/s system must have a bandwidth
greater than 110 MHz. A receiver for a 622 Mb/s system must have a
bandwidth greater than 415 MHz. On the other hand, any frequency
component above 110 MHz for 155 Mb/s systems or above 415 MHz for
a 622 Mb/s systems contributes excess noise to the output. The excess
noise needlessly reduces the sensitivity of the receiver. The receiver
designer may therefore improve the PIN-TIA sensitivity by placing a low
pass noise filter on the output.

Precautions for Use
ESD protection is imperative. Use of grounding straps, anti-static
mats, and other standard ESD protective equipment is required
when handling or testing an InGaAs PIN or any other junction
photodiode. Fiber pigtails should be handled with less than
10 N pull and with bending radius greater than 1”. Soldering
temperature of the leads should not exceed 260
o
C for more
than 10 seconds.
