Ternary Content Addressable Memory

Renesas Technology America (San Jose, CA) now offers the TCAM (Ternary Content Addressable Memory) Series of memory products to enable high-speed packet processing for networking equipment such as routers and switches. The first product in the series is the R8A20410BG TCAM, which has a capacity of 20 Mbits and delivers high-speed search performance of up to 360 MSPS (mega-searches per second)/Table. TCAM memory cells can store three data states: 0, 1, and X (“Don’t Care”). It is suitable for applications such as networking equipment because it achieves deterministic, high-speed searches by using simultaneous parallel operation to compare data strings input from an external device with data strings stored in the memory and outputting the matches.

LPDDR2 Compliance and Protocol Test Tools

Agilent Technologies Inc. (Santa Clara, CA) has introduced a new comprehensive low-power double data rate 2 (LPDDR2) compliance and protocol test application package and industry-first LPDDR2 ball-grid array (BGA) probes. The Agilent N5413B LPDDR2 test application, which runs on Agilent Infiniium 9000 Series oscilloscopes, provides LPDDR2 physical-layer compliance measurements. The Agilent B4623A LPDDR2 bus decoder and the B4622A DDR protocol compliance tool, which run on the Agilent 16900 Series logic analyzers, provide debug and protocol compliance measurements.

Single-Chip OTN Platform

Zarlink Semiconductor (Ottawa, Canada) has introduced ClockCenter, a platform for high-speed optical transport network (OTN) and communications equipment. ClockCenter synchronous products synchronize “any rate, any port, all the time,” meaning the single-chip solution accepts and generates any frequency (1 kHz to 720 MHz) required to support all communication services delivered over optical and Ethernet networks. The ClockCenter free run products are suitable for designing equipment for a range of applications that have traditionally relied on multiple oscillators, logic converters, and fan outs to time processors, memory chips, PHY chips, and more. The free run clock products allow equipment manufacturers to replace multiple external components with an integrated single-chip device.

Product of the Month: Wireless MEMS Sensor for Glaucoma Diagnosis

STMicroelectronics (Geneva, Switzerland) has developed a wireless MEMS sensor that acts as a transducer, antenna, and mechanical support for the SENSIMED Triggerfish® continuous eye pressure monitor from Sensimed AG. The solution will enable better management of glaucoma patients via earlier diagnosis and treatment that is tailored to each patient. The solution is based on a “smart” contact lens that uses a tiny embedded strain gauge to monitor the curvature of the eye over a period of 24 hours, providing disease management data that is not obtainable using conventional ophthalmic equipment. The lens also contains an antenna, a tiny dedicated processing circuit, and an RF transmitter that communicate the measurements to a receiver worn around the patient's neck. Because it is powered via the received radio waves, it does not need to be connected to a battery.
