SERCOS
Features
SERCOS is a Serial Realtime Communication System, a Fully compliant to SERCOS optical specifications
standard digital interface for communication between
controls and drives for numerically controlled machines.
The SERCOS interface specification was written by a joint

working group of the VDW (German MachineTool Builders Auto-insertable and wave solderable
Association) and ZVEI (German Electrical and Electronic
Manufacturer’s Association) to allow data exchange
between NC controls and drives via fiber optic rings, with
Data transmission at symbol rates from DC to over
2 MBd for distances from 0 to over 20 metres
isolation and noise immunity. The HFBR-0600Z family
of fiber optic transmitters and receivers comply to the

Description
Tempest-secure data processing equipment
Isolation in test and measurement instruments
Robotics communication
The HFBR-0600Z components are capable of operation at
symbol rates from DC to over 2 MBd and distances from
0 to over 20 metres. The HFBR-1602Z and HFBR-1604Z
transmitters contain a 655 nm AlGaAs emitter capable of
efficiently launching optical power into 1000 mm plastic
optical fiber. The optical output is specified at the end of
0.5 m of plastic optical fiber.
The HFBR-1604Z is a selected version of the HFBR-1602,
with power specified to meet the SERCOS high attenua-
tion specifications.
The HFBR-2602Z receiver incorporates an integrated
photo IC containing a photodetector and DC amplifier
driving an open-collector Schottky output transistor. The
HFBR-2602Z is designed for direct interfacing to popular
logic families. The absence of an internal pullup resistor
allows the open-collector output to be used with logic
families such as CMOS requiring voltage excursions higher
than V . The HFBR-2602Z has a dynamic range of 15 dB.

CAUTION: The small junction sizes inherent to the design of this component increase the component's susceptibility
to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and
assembly of this component to prevent damage and/or degradation which may be induced by ESD.

3. Thermal resistance is measured with the transmitter coupled to a connector assembly and fiber, and mounted on a printed circuit board.
4. Pins 2, 6, and 7 are welded to the cathode header connection to minimize the thermal resistance from junction to ambient. To further reduce the
thermal resistance, the cathode trace should be made as large as is consistent with good RF circuit design.
5.
P is measured with a large area detector at the end of 0.5 metre of plastic optical fiber with 1 mm diameter and numerical aperture of 0.5.
T
6. When changing W to dBm, the optical power is referenced to 1 mW (1000 W). Optical Power P(dBm) = 10 log [P (W)/1000 W].
7. Measured at the end of 1mm plastic fiber optic cable with a large area detector.
8. 8 mA load (5 x 1.6 mA), R = 560 .

9. Propagation delay through the system is the result of several sequentially occurring phenomena. Consequently it is a combination of data-rate-
limiting effects and of transmission-time effects. Because of this, the data-rate limit of the system must be described in terms of time differentials
between delays imposed on falling and rising edges. As the cable length is increased, the propagation delays increase. Data-rate, as limited by
pulse width distortion, is not affected by increasing cable length if the optical power level at the receiver is maintained.
10. Pulse width distortion is the difference between the delay of the rising and falling edges.
11. Both HFBR-1602Z and HFBR-1604Z meet the SERCOS "low attenuation" specifications when operated at 35 mA; only HFBR-1604Z meets the
SERCOS "high attenuation" limits when operated at 60 mA.
