Design of Base I/O Libraries Design How-To 11/20/2003 Post a comment Cell libraries clearly play a critical role in IC design today. They serve as the fundamental building blocks for any new chip design. Most developers have chosen a standard cell library early in the design process, frequently based on which IC foundry they are working withand verified that the library works smoothly within their design flow.
LVDS fan-out buffers support high-availability systems Product News 11/19/2003 Post a comment IDT enters the high-performance clock distribution market with the introduction of a family of industry leading, low-voltage differential signaling (LVDS) fan-out buffers. IDT believes it is the first to offer LVDS fan-out buffers with redundant clocking and glitchless switchover. This feature reduces system failure and increases reliability.
Analog mux parts claim reduction in signal feed-through Product News 11/17/2003 Post a comment Intersil's new MightMUX devices claim a 99 percent reduction in off-state leakage current and a 99 percent reduction in off-state signal feed-through " at least, compared with Intersil's previous-generation switches. But then, a 2-pA leakage current is respectably low.
Get ready for a new logic family: AUP devices keep your handhelds running longer Product News 11/13/2003 Post a comment Texas Instruments' AUP (Advanced Ultra Low Power) logic devices may give battery-powered devices up to 73 percent longer life than other kinds of 3.3V logic. Intended to be "unnoticeable" in battery-powered portables, the AUP devices reduce the input capacitance on the logic gates and consequently the drive current required. The new devices could be powered from sub-1V supply rails.
Parallel port transceiver features power-on protection feature Product News 11/10/2003 Post a comment STMicroelectronics' 74LVC161284TTR is a low-voltage, high-speed IEEE1284 transceiver. A "Z" version, the 74LVCZ161284ATTR is almost identical, but features an error-free power-up function as well. Each of these transceivers can replace the function of two previous-generation 74ACT1284 devices. Both parts support both IEEE1284-I and -II (level one and level two) bi-directional parallel communications between personal computers and peripherals.
Serdes claims 10-Gbit backplane channels News & Analysis 11/4/2003 Post a comment Agere Systems has built a 90-nanometer serializer/deserializer chip that can deliver 12.5-Gbit/second throughput, giving designers a way to provide 10-Gbit channels across backplanes in networking-box architectures.
Fail-safe 40Mbits/s transceivers support Profibus, RS-485/RS-422 Product News 11/4/2003 Post a comment Maxim's MAX3465-MAX3469, announced this week are fail-safe, 40Mbits/s Profibus transceivers. These devices are high-speed, differential-bus transceivers for RS-485 and RS-422 communications, and are designed to meet TIA/EIA-422-B, TIA/EIA-485-A, V.11, and X.27 standards. From eeProductCenter's postings, here's the scoop.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
