Functional Description
Design
The receiver contains an InGaAsP
photodetector, transimpedance
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
preamplifier circuit.
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 identically, 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.
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.
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 performance. Useful
guidelines are contained in ECL
manufacturer design manuals.
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 and hand
soldering are recommended for
this part.
