Compact transceivers offer robust
performance
Parallel networks, like SCSI "fast 40" systems, benefit from the 40Mbit/s data rate and the low transceiver and receiver skews, as well as the 4nS part-to-part skews.
Intersil has introduced the ISL3159E and ISL3179E RS485/RS422 transceivers These next-generation interface ICs combine 40Mbit/s transmission performance over the industry's widest temperature range (-40C to +125C) along with 15kV IEC61000 ESD protection and a DFN package option that is up to 70% smaller than standard 8-lead SOIC offerings

Programmable up-converter simplifies basestations
Intersil has added a new highly integrated quad up-convertor to its CommLinkT family of digital radio ICs for fixed basestation applications.
The ISL3159E has enhanced output differential voltage drive (Vod).
The transceiver Vod is specified as >2.1V; a 40% increase over the standard 1.5V specified by the RS485 protocol.
In addition, the receiver outputs deliver superior low state currents (typically >30mA at Vol = 1V) to ease the design of optically-coupled, isolated networks.

Wireless LAN technology for the workplace
Intersil is introducing a new brand of wireless products called Prism/work specifically designed to meet the growing need for wireless LANs in the workplace.
These enhancements and rugged features make the ISL3159E an ideal fit for Profibus DP and FMS applications.
Other applications will also profit from the increased noise immunity and enhanced data integrity provided by the extra large Vod.
Parallel networks, like SCSI "fast 40" systems, benefit from the 40Mbit/s data rate and the low transceiver and receiver skews, as well as the 4nS part-to-part skews.
With the option of a 5V supply (ISL3159E) and a 3.3V supply (ISL3179E), these devices are the only RS485 transceivers that maintain a 40Mbit/s data transfer rate at temperatures up to 125C while consuming only 4mA of quiescent supply current.
This performance enables high-speed data transmission in the harshest environments.
The tiny 3x3mm DFN package integrates a thermal slug that enables this package to provide approximately a 40% improvement in thermal resistance compared with the SOIC package to create a very reliable, robust solution.
The dependability of the devices is also extended by the fact that they exceed IEC61000 ESD standards with 15kV protection on all RS485 input and output pins.
Other key features of these rugged transceivers include a full fail-safe receiver, hot plug circuitry to ensure the transceiver and receiver outputs stay in high-impedance as the power supply stabilises, and current limiting and thermal shutdown for driver overload protection.
These transceivers are available in both the industrial (-40C to +85C) and extended (-40C to +125C) temperature ranges.
The multiple Pb-free package options include an industry-standard eight-lead SOIC, an eight-lead MSOP that is 50% smaller then the SOIC and the 3 x 3mm 10-lead DFN package.
The ISL3159E and ISL3179E are available now specified for operation up to +125C.
