The synchronous frequency divider, shown in Figure 1, is considered more desirable than the asynchronous device.
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.
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.
This presents a problem for PC users because PCs are essentially asynchronous devices.
Users employing the AS/400 improvements will be able to transfer data between the server and such asynchronous devices as time clocks, badge readers, bar-code scanners, and robots.
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 server can also be used to provide network users with access to modems and other asynchronous devices.
