RCV1551

Fiber Optic “Light to Logic” Receiver

Data Sheet

Description

The RCV1551 receiver provides optical signal conversion

and processing. It contains an InGaAs PIN photodiode and

high sensitivity, wide dynamic range, transimpedance

amplifier, capacitively coupled to limiting amplifier stages

with PECL output drivers. Also provided is a loss of signal

alarm.

The planar PIN photodiode operates throughout the

1200 nm to 1600 nm wavelength band. A bipolar wide

dynamic range transimpedance amplifier optimized for

155 MBd operation provides low noise front end gain for

the RCV1551.

A low pass filter maximizes the signal to noise ratio

while minimizing intersymbol interference. The interface

amplifier provides signal conversion and buffering for the

PECL complementary data outputs. A complementary

PECL alarm output is also provided.

The receiver operates in both ECL and PECL configura-

tions. A 50/125 micron multimode fiber pigtail is included,

assuring compatibility with multimode and single mode

fiber optic systems.

Pin Descriptions

Pins 5, 17, 18, 19, 20 NC:

These pins are not connected and should be left open

circuit on the application PCB.

Pin 11, +5 V:

This pin should be connected to +5 V supply. The network

shown below should be placed as close as possible to Pin

11.

Pins 1, 2, 3, 4, 6, 8, 13, 15, 16 GND:

These pins should be connected to the circuit ground.

Pins 12,14 ALARM, ALARM:

These pins provide complementary differential ALARM

and ALARM outputs. This is the low light alarm. ALARM

goes to a logic low (3.3 V nominal) state when the optical

power drops below the threshold level (insufficient optical

power).

The optical power must increase to a higher level than the

level where the alarm went low before ALARM will return

to a logic high. This difference is the alarm hysteresis.

Pins 7, 9, DATA, DATA:

These pins provide complementary PECL DATA and DATA

outputs. The DATA output is non inverting, an optical pulse

causes the DATA output to go to the PECL logic high state

(+4 V nominal).

Pin 10, PD Bias:

This pin must be connec ted to any voltage

from 0 V (GND) to -6 V. This provides the photo-

diode bias. The current drawn is directly propor-

tional to the average received photocurrent

I = Responsivity x Mean Power. The responsivity will be

between 0.7 A/W and 1.0 A/W.

Functional Description

Design

The receiver contains an InGaAs photodetector, tran-

simpedance amplifier and interface amplifier circuit. It is

designed with a multimode fiber pigtail to allow maximum

flexibility in connector options.

The interface amplifier is capacitively coupled to the pre-

amplifier circuit.

Circuit Layout

The RCV1551 uses very high bandwidth circuitry to

achieve its high level of performance. Care must be taken

to ensure stable operation. The use of ground planes and

transmission line interconnects is required. The use of a

standard evaluation board is highly recommended for

those users who are not familiar with these techniques.

Signal traces should conform to ECL design rules to

prevent reflections and ringing from degrading perfor-

mance. Useful guidelines are contained in ECL manufac-

turer design manuals.

Terminating the Outputs

The data outputs of the RCV1551 are PECL compatible.

Care should be taken to match termination impedances to

the interconnect to minimize reflection effects. Both serial

data outputs (DATA and DATA) should be terminated iden-

tically, even if only one output is used, in order to balance

the drive currents drawn from the module. This will lower

the power supply noise generated by the receiver and

improve performance at low optical input power levels.

Manufacturing

The fiber pigtail on the device requires normal fiber

handling considerations. Care should be taken to avoid

tight bends as well as excessive tension on the fiber

pigtail.

The allowable temperature range for the RCV1551 is

limited by the material used in the pigtail. Exposure to

temperatures over +85°C is not recommended. Low profile

sockets or hand soldering are recommended for this part.

Power Supplies

The RCV1551 will operate to specifications with a single

+5 V power supply (Pin 10 Grounded). The -5 V PIN bias is

provided to maintain functional compatibility with second

sources.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause catastrophic damage to the device. Limits apply to each parameter in

isolation, all other parameters having values within the recommended operating conditions. It should not be assumed that limiting

values of more than one parameter can be applied to the product at the same time. Exposure to the absolute maximum ratings for

extended periods can adversely affect device reliability.
