operate at much lower levels. In accordance with its standard, LVDS
uses a differential 200 mV level, whose direct current share is ultimately
cancelled out. During LVDS signal transmission, this results in a much
lower power loss than in conventional single-ended signals. Most
FPGAs can work with LVDS signals without any difficulty. As a result,
virtually no modifications are necessary on the evaluation side. This is
therefore a minor change resulting in a major benefit. This innovative
LVDS isolated delta-sigma modulator is available from EBV Elektronik
under the EBVchip program with the project name Hunter or ACPL-
798J. Hunter conforms to insulation class IIIa in accordance with DIN
VDE 0110 and works with external clock sources in the 15...25 MHz
range; the clock pulse is reliably transmitted across the galvanic isolation.
Thanks to this, the module can perform the data acquisition synchro-
nously with any digital controller. The module even transmits the
encoded modulator data across the galvanically isolated route. The
data is recovered, decoded and converted into a serial data stream on
the other side. With a typical signal/noise ratio of 78dB with an appro-
priate digital filter, differential non-linearity of 0.9 LSB with a resolution
of 16 bits, no missing codes (12 bits ENOB) and a typical gain error of
2%, the Hunter, which has been designed for ambient temperatures of
-40...+105 °C, is suitable for a large number of industrial applications.

TRINAMIC: single-axis motion control IC for cost-sensitive
designs
TRINAMIC Motion Control announces a low cost single-axis motion
control IC. The new TMC4210 motion controller performs all real-
time position and velocity stepper motor calculations, relieving a host
microcontroller from the software design complexity required to im-
plement a motor control system. The TMC4210 is compatible with a
wide selection of TRINAMIC and third-party motor drive ICs that use
ce.

(HF RFID) readers. The SL900A is an EPC Gen 2 Class 3 tag for use
with RFID readers.
Maxim: reference design for industrial control and automation
applications
Designers now have a way to reduce power, system cost, and size for
programmable logic controller digital-input subsystems, with the
Corona reference design by Maxim Integrated Products. This design
reduces isolated channels and leverages analog integration for industrial
control and automation applications.
TI: motor driver family integrates power management and CAN
interface
Texas Instruments expanded the industry’s first automotive motor
driver family intended to help TI customers design automotive appli-
cations to meet the functional safety requirements of ISO 26262.
