Using dual port memory as interconnect Design How-To 4/26/2005 Post a comment Interconnect ICs enable data transfer between a variety of processing elements that do not have a compatible interface. They are also used to extend system bus that does not have the required fanout or sufficient bandwidth to meet the data transfer need. Popular interconnect components are dual-port buffers, SERDES, and PCI bridge chips. Without the usual circuit diagrams or waveforms, a Cypress engineer suggests how.

From the April issue of Planet Analog magazine, a Cypress Semiconductor engineer offers insights into an SoC architecture that implements spread-spectrum over 10 meters - without interfering with other devices in its frequency range.
500-kHz 16-bit analog I/O board is low-profile PCI plug-in Product News 4/20/2005 Post a comment Here's news of a high-resolution data converter and control board that's priced at less than $700 a pop. The new plug-in is a PCI bus-compatible multi-function analog I/O board that imparts 16-bit precision to PC-based measurement, analysis, monitoring and control applications. Either commercial temperature range or industrial temp range versions can be ordered. PCI-X and PC/104 versions are available, too.
Building JPEG/Motion JPEG Into The Security Camera Design How-To 4/15/2005 Post a comment The Security & Surveillance industry is asking for higher and higher resolution images. The need for JPEG/Motion-JPEG compression is growing rapidly. Individual frame data is preferred to MPEG based algorithms because of its ease of use in reconstructing individual frame data for law
enforcement purposes. The existing infrastructure for the Security & Surveillance industry is based on CCTV standards. They are now beginning to migrate towards 10/100 Ethernet solutions. Here's how ISG created cam
Storage disk arrays pose challenges for chassis design Blog 4/11/2005 Post a comment We had heard from Teradyne's Chris Heard at DesignCon about some of the issues involved in the packaging of RAID storage cabinets. A visit from Maxtor confirmed some of the things we had been hearing: Though drives were getting smaller, they were getting packed tighter together on a rack. Heat and cable routing is becoming a problem. Here is Chris' commentary from Planet Analog magazine.
Less-than-$1500 data-acq board packs USB, 300-MHz DSP Product News 4/11/2005 Post a comment Data acquisition board maker Data Translation is now shipping a less-than-$1500 data acquisition and control board. As a 2-channel-in/2-channel-out board, it's intended for price-sensitive systems. "The E in the product designation stands for economy," says DT product manager Tim Ludy.
PC-hosted 7-1/2-digit DMMs drop into PXI, cPCI slots Product News 4/8/2005 Post a comment On the heels of its recently released 7-1/2-digit precision digital multimeter, as well as the competing follow-on product from National Instruments, DMM maker Signametrics is rolling out two new 7-1/2-digit DMMs, this time in PXI and CompactPCI form-factors.
High-speed/RF digitizers tout 25-Gbit/s optical data streaming Product News 4/6/2005 Post a comment Digitizer maker Acqiris has two new data-acquisition plug-ins that carry optical output links. These give the modules the ability to stream data at rates as high as 25-Gbits/s! That's just the ticket for applications such as I/Q demodulation in software-defined radios or for radar and SIGINT.
Settable equalizer increases copper throughput to 6.25 Gbits/s Product News 4/4/2005 Post a comment A settable analog equalizer boosts the integrity of NRZ data patterns at 6.25 Gbits/s data rates, and legacy application frequencies of 2.5 Gbits/s, 3.125 Gbits/s, and 5 Gbits/s. The device has the small size and low power consumption of fixed-frequency equalizers, and the flexibility of self-adaptive types " without any of their data errors. Steve Ohr took a briefing with company principals, and generated this review.
FM tuner simplifies radios in portable devices Product News 4/4/2005 Post a comment Designers seeking to include FM radio functionality in their portable devices, such as handsets, MP3 players, PDAs, and notebook PCs, should take a serious look at this latest FM tuner family from Silicon Labs, which adds FM radio tuning and requires only one external capacitor.
PCI bus motion-control board eventually targets PC/104 Product News 4/1/2005 Post a comment Here's news of PCI bus motion controller plug-in card that is the basis of an embedded controller using the compact PC/104 form-factor. The new card packs dual bi-quad filters, and is available in 1-axis, 2-axis, 3-axis, and 4-axis versions supporting brush-type, brushless DC, micro-stepping, pulse, and direction motors.
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.
