Maxim Integrated Products has announced the MAX22500E, MAX22501E and MAX22502, a set of RS-485 transceivers that enable Industrial designers to achieve 2x faster data rates and extend cable length by up to 50%. With motion control systems requiring more accuracy over longer distances, system designers are challenged to maintain faster data rates and achieve robust communications with longer cables. A production site, for example, may not efficiently function with a slow data rate and short cables as it must transfer accurate information quickly and over a long distance.
The MAX22500E/MAX22501E (half-duplex) and MAX22502E (full-duplex) ESD-protected RS-485/RS-422 transceivers extend the reach of communication up to 100 Mbps over 50 m. This provides the industry’s fastest data rates for accurate, cost-effective, and robust communication across long cables for a variety of motion control applications. The settable pre-emphasis feature within the MAX22500E and MAX22502E enables 2x faster data rates compared to competitive solutions for increased encoder resolution and reduced latency. Pre-emphasis extends cables up to 50% longer to communicate over longer distances. A large receiver hysteresis (250 mV) provides superior robustness to EFT. In addition, by improving the signal integrity and robustness, system designers can achieve the same level of performance with lower-cost cables. The transceivers operate over the -40℃ to +125℃ temperature range.
Robust communications: Extends the reach to 100 Mbps over 50 m (or 50 Mbps over 100 m); Settable pre-emphasis improves data integrity with high data rates; 250 mV receiver hysteresis for EFT robustness
High Performance: Fastest 100 Mbps data rate for higher resolution/accuracy communication; flexible low voltage logic supply interface down to 1.6 V; Improved signal integrity enables less expensive cable costs
Small Size: Reduced footprint with small 8-, 10- and 12-pin TDFN packages
Intersil, a subsidiary of Renesas Electronics, has announced two new high-speed, isolated RS-485 differential bus transceivers that provide 40 Mbps bidirectional data communication for Industrial Internet of Things (IIoT) networks. The ISL32741E offers 1,000 VRMS working voltage and 6 kV of reinforced isolation, more than 2x higher than competitive solutions. The higher working voltage and reinforced isolation is required for today’s most rigorous medical and high-speed motor control applications. The ISL32740E with 2.5kV of isolation and 600VRMS working voltage comes in a small package, enabling high channel density for programmable logic controllers (PLCs) in factory automation applications.
The ISL3274xE transceivers provide additional advantages over other isolation technologies, including ultra-low radiated emission and EMI susceptibility, support for up to 160 devices on the bus, and an extended 125°C temperature range. These devices leverage giant magneto-resistance (GMR) technology that provides galvanic isolation to keep the communication bus free from common-mode noise generated in electrically noisy factory and building automation environments. The ISL32740E and ISL32741E 40 Mbps RS-485 transceivers are available now with prices ranging from $3.79 to $4.79 depending on package type and temperature range. Evaluation boards are available for $99.
