Maxim Integrated Products now offers the MAX3747/MAX3747A 3.3-V, low-power, multirate limiting amplifiers with a programmable loss-of-signal (LOS) indicator. Pin-compatible to the Micrel SY88993V limiting amplifier, these devices provide higher gain, better bit-error-rate performance, and lower jitter than the SY88993V.
Operating from a single 3.3-V supply, the MAX3747/MAX3747A have better than 4-mV input sensitivity and 120-mV root-mean-square input-referred noise while consuming only 60 mW. Each amplifier has a programmable signal-detect function that can be set to different assert and deassert levels. At the same time, the amplifiers maintain a 2-dB hysteresis. The MAX3747 features low 13-ps deterministic jitter and less than 3.5-ps root-mean-square random jitter. The devices accept input voltages from 4 to 1200 mV. They provide 500-mV peak-to-peak (MAX3747) or 800-mV peak-to-peak (MAX3747A) output swing.
The MAX3747/MAX3747A amplifiers are packaged in a 3-mm, 10-pin microMAX. They operate over the extended temperature range (−40°C to +85°C). Prices start at $4.50 (1000-up, FOB USA). An evaluation kit is available to speed designs. For more information, go to www.maxim-ic.com.

The CellularRAM specification co-development team, which includes Cypress Semiconductor Corp., Infineon Technologies, and Micron Technology, Inc., welcomed its new member, Renesas Technology Corp. Renesas is the first Asia-headquartered manufacturer that is developing a family of CellularRAM devices for next-generation mobile handsets. The CellularRAM products are high-performance, low-power memory solutions designed to meet the growing memory density and bandwidth demands of future 2.5G and 3G handset designs. Like other specification co-development members, Renesas will design its devices using its own technology. It also will manufacture the products in its own fabrication facilities.
CellularRAM devices are currently available. To learn more about the densities and configurations available, visit www.cellularram.com.

Linear Technology's new LTC2904/LTC2905 and LTC2906/LTC2907 products are space-saving dual-supply monitors. The LTC2904/LTC2905 feature nine combinations of input threshold levels. The LTC2906/LTC2907 provide one input that is adjustable to as low as 0.5 V and another with three possible voltage selections. All of the ICs offer selectable supply tolerance of 5%, 7.5%, and 10%, thereby allowing for possible margining.
The tight ±1.5% voltage-threshold accuracy and glitch immunity ensure reliable reset operation without false triggering. The LTC2904/LTC2905 and LTC2906/LTC2907 are offered in 8-pin ThinSOT and DFN packages. Their small size makes them perfectly suited for handheld devices and portable intelligent instruments as well as any dual-supply voltage system.
Prices for the LTC2904/LTC2905 and LTC2906/LTC2907 begin at $1.35 each in 1000-piece quantities. For more details, go to www.linear.com.

Xilinx, Inc. is offering a free, fully functional Configurable Physical Coding Sublayer (CPCS) reference design for a multi-mode PCS block. It is implemented in Xilinx Virtex-II Pro field-programmable gate arrays (FPGAs). The CPCS can be dynamically configured to support three types of PCS layers including Fibre Channel (1.0625 and 2.125 Gbps), Gigabit Ethernet (1000BASE-X), and ESCON/SBCON (200 Mbps). The CPCS reference design is ideal for applications including Ethernet/Fibre Channel switches, multi-service provisioning platforms (MSPPs), SONET/SDH terminals, add-drop multiplexers (ADMs), cross connects, CWDM/DWDM transport equipment, and IP routers. The fully documented CPCS reference design is now available free of charge. All documentation and design files can be downloaded from the Xilinx web site at www.xilinx.com/esp/cpcs.

Actel Corp. reported results of a third-party investigation that verified that field-programmable gate arrays (FPGAs)—based on flash and antifuse technologies as with Actel products—are immune to the configuration upsets caused by high-energy neutrons. Such neutrons are naturally generated in the earth's atmosphere. The study also determined that SRAM-based FPGAs are vulnerable to neutron-induced configuration loss under high-altitude conditions and in ground-based applications. The tests, which followed the industry-prescribed JESD-89 test methodology, were conducted in February of this year by iRoC Technologies. The tests were all conducted at the Los Alamos Neutron Sciences Center at Los Alamos National Laboratory in New Mexico. The results of the independent study are documented in the report entitled, "Radiation Results of SER Test of Actel, Xilinx, and Altera FPGA Instances." This report is now available free of charge at http://www.actel.com/products/rescenter/ser/index.html. For more information on Actel's FPGA technologies, go to www.actel.com.
