Security Processor With IPsec Or SSL Tops Out At 10 Gbits/s
With the Nitrox II family of security processors, networking-equipment manufacturers can easily build security into routers, switches, Web servers, load balancers, firewalls, storage-area networks, and virtual private network gateways. The processors eliminate the usual security-processing bottleneck that occurs when encryption is offloaded to a host processor. The Nitrox II is positioned between the media-access control and host processor and completely implements security processing, bypassing the host processor and eliminating the bottleneck. Both IPsec and SSL are included, and there’s support for all encryption and hashing algorithms, such as 3DES, AES, ARC4, SHA-1, SHA-2, and MD-5. Two versions of the device are available. The CN2130 costs $295. The CN2560 costs $795. Pricing is in 1000-unit lots.

Timing Synchronization Gets A Lift From Low-Jitter Clock
Engineers seeking a low-jitter signal source in the 1.544- to 77.79-MHz range for communications line cards, service termination cards, chained servers, and other equipment can opt for the SFT100 complete clock solution. It uses advanced phase-locked loop (PLL) and phase-detection circuitry combined with the company’s fundamental-mode variable crystal controlled oscillator. The output frequency, locked to a user-selectable input reference clock, is typically a LVCMOS signal of 8, 16, 32, or 64 kHz, or 19.44 MHz, by request. Jitter is less than 0.001 UI. If lock is lost, the free-run output meets the GR-1244-CORE Sonet specification for clock holdover of ±20 ppm. The unit is packaged in a 14-pin 20- by 19- by 4.8-mm SMD FR4 package. Samples are available now. Cost is $40 each in 1000-unit lots.

Cell-Phone SiGe Power Amps Elevate Price/Performance Ratio
The SE5102 and SE5103 power amplifiers (PA), specified for use in IS-95 and cdma2000 CDMA cell phones operating in the 824- to 849-MHz range, are the latest additions to the RangeCharger family. They’re designed to meet the needs of designers fighting the battle of lower handset costs and power consumption. The SE5102/SE5103 are complete PA modules that include a complete biCMOS silicon-germanium (SiGe) amplifier chip and 50-W input and impedance matching networks. These class AB linear amplifiers are 39% to 40% efficient and provide 28-dBm output power and -135-dBm/Hz noise power performance. The SE5102 PA comes in a 3- by 3-mm QFN package and costs $0.75 in 10,000-unit quantities. The SE5103 module, housed in a 10-pin 4- by 4- by 1.4-mm LGA package, costs $1.50 in 10,000-unit lots.
