Fleet, UK AVX offers an ultra-small crystal oscillator designed for telecommunication systems. Designated the CX-2520SB , the surface mount device contains a ceramic package that offers high reliability with repeatable performance in a compact package. Resonating at a frequency range of 26.000 -60.000 MHz, the CX-2520SB oscillator provides re-flow compatibility for mobile communications, Bluetooth and wireless local area network applications. The lead-free, RoHS-conforming oscillator has motional series resistances of 100 Ohm at 26.000 - 34.999 MHz and 50 Ohm at 35.000 - 60.000 MHz with a load capacitance of 8 pF. Measuring 2.5 x 2.0 mm (±0.1 mm), the 0.45 mm (±0.1 mm) thick crystal oscillator has a frequency tolerance of ±10 ppm at 25 °C and an operating temperature range of -30 to 85 °C. Typical pricing for the CX-2520 starts at $1.00/each for 1,000 pieces and $.70 for 10,000 pieces. AVX Ltd , Fleet, UK. www.avx.com.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
