Crystek has released the company's
CVCO55FLM-0137-0171 which operates from 137 MHz to 171 MHz with a
control voltage range of 0.5 V to 4.5 V. The VCO (Voltage Controlled
Oscillator) features a typical phase noise of -118 dBc/Hz at 10 KHz
offset and claims to have excellent linearity.
Crystek's CVCO55FLM VCOs contain an extra modulation port
(TX modulation), making the family an ideal choice for transmitter
applications. The modulation port has a negative slope and a typical
modulation sensitivity of -25 KHz/V.
The model CVCO55FLM-0137-0171 is packaged in the industry-standard
0.5-inch x 0.5-inch SMD package. Output power is typically 0 dBm, and
input voltage is 5 V, with a max. current consumption of 20 mA. Pulling
and Pushing are minimized to 1.5 MHz and 0.5 MHz/V, respectively. Second
harmonic suppression is -15 dBc typical.
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.
