Description

The Si858x products are devices that combine robust,

fully compliant RS-485 transceivers with signal ?

isolation. These devices are ideal for industrial ?

automation applications that require isolated ?

interfaces for FieldBus systems that form a ?

communication network for connecting sensors, ?

actuators, and controllers.

These devices are ideal for isolating nodes on?

FieldBuses based on the RS-485 standard, such as ?

ProfiBus or ModBus. These transmission lines can be ?

susceptible to electrical noise transients especially in

harsh environments such as a factory floor, or in ?

sensitive environments such as process control or data

acquisition. Isolation provides a means of protection

from such transients and noise that could corrupt ?

signal integrity.

These isolated transceivers can operate with a 3.3 V or

5.0 V nominal power supply and have robust bus fault

tolerance up-to ±30 V for protecting against harmful

transients in noisy environment where such systems

are often utilized. The bus pins are also protected up

to 15 kV HBM ESD. Product options are available for

half duplex and full duplex mode in industry standard

footprints and incorporate slew rate controlled drivers

with 1 Mbps data rate capability for reducing the EMI

profile or options for high data rate up to 10 Mbps

with no slew rate control implemented. These ?

products also offer safety and protection features,

such as receiver fail-safe and thermal protection.

These devices utilize Skyworks' proprietary silicon ?

isolation technology, supporting up to 5 kVRMS (for

one minute) isolation voltage per UL1577. This technology

enables high CMTI (>100 kV/μs), low propagation

delays and skew, reduced variation with

temperature, and age and tight part-to-part matching.
