Additional working groups are forming to focus on definition of a User-Level Application Programming Interface (API), Instrument Portability/Abstraction Layer, Tooling (device interface) Abstraction Layer and Asynchronous Device Test Interface.
During the debug and characterization phase, it can be nearly impossible to accurately test the signal integrity of devices that run asynchronous to ATE system timing, but with the SIA family's hardware and Gigaview(TM) software tools, asynchronous device testing is possible for true compliance to today's demanding specifications.
All four of ISSI's focus markets benefit from the 8Mbit high-speed asynchronous device, providing a greater selection for customer satisfaction," said Sanjiv Asthana, ISSI's vice president of marketing.
The IDT 18-Mbit, synchronous device operates at an industry-leading 166 MHz, while the asynchronous device runs at access times as low as 10ns, making them suitable for high-performance designs such as wireless base stations, network switches and routers, and other telecom, datacom and networking applications.
With the increasing usage of SDRAM in today's applications, it became obvious to us that the asynchronous Flash being used for code storage was the only asynchronous device in the design.
The unmatched throughput of our flagship 72-Mbit QDR-II+ devices enables innovative usages, such as reconfigurable computing, while our 4-Mbit fast asynchronous devices deliver faster speed than any competing solutions.
At half the cost of traditional statmux equipment, Patton's IpStatMux(TM) is an obvious candidate for replacing aging RS-232 multiplexers in connections to PLCs, RTUs, meters, barcode scanners, gas pumps, cash registers, terminals, and similar asynchronous devices.
According to Randy Ross, manager of RDS implementation, data-compression equipment has enabled the group to double the number of high-resolution graphics terminals on a single line, as well as linking both synchronous and asynchronous devices over the same 9600-b/s line.
Both the asynchronous devices with and without RTC are offered in data bus widths of 8 bits, 16 bits and 32 bits, and at different power supply levels of 2.
Attached asynchronous devices can functions as IBM 3278 display stations, 3279 color display stations or 3287 printers.
Serial port device types number in the thousands and include products such as: remote terminal units, meters, barcode scanners, gas pumps, oscilloscopes, spectrum analyzers, cash registers, terminals, and similar asynchronous devices.
The Femto 2000 provides the ability to dramatically reduce test time and improve the quality of jitter and critical timing tests by production ATE systems for both synchronous and asynchronous devices.
