Transmitter and receiver cut cost of SERCOS data links
|
|
Avago Technologies offers a fibre-optic transmitter and receiver supporting SErial Realtime COmmunications Systems (SERCOS) up to 16Mbaud over Plastic Optical Fibre (POF) or Hard-Clad Silica (HCS) for cost-sensitive industrial infrastructures. |
The HFBR-1506AMZ
transmitter incorporates
a 650nm LED with high
light-output power
enabling the use of either
1mm POF or 200µm HCS.
The temperature coefficient
of optical power is -0.02dB/°C,
ensuring predictable performance
in a variety of industrial environments.
The HFBR-2506AMZ receiver operates from
a 5.5V supply and produces a logic-compatible
output. It also includes a unique circuit to
correct Pulse-Width Distortion (PWD) of the
first bit after a long idle period. This enables
operation from DC to 16MBaud with low PWD
for arbitrary data patterns.
Both the transmitter and receiver are coated
with a layer of conductive alloy for enhanced
ESD performance, and are compatible with
SMA connectors.
