The CNT-90 is a new tool for measurement, analysis and calibration of frequency, time interval or phase, whether in test systems, on the R and D bench, in the calibration lab or in the field.
Budget price for general-purpose spectrum analyser
The GW Instek GSP-827 general-purpose spectrum analyser is available from Aspen Electronics.
The VS720 is footprint-compatible with Vectron's existing VS700 SAW oscillator, making it a plug-in replacement in designs for PLL (phase lock loop) applications that require lower VCXO gain, improved holdover temperature stability and/or initial accuracy.
The latest design employs bulk acoustic wave (BAW) and surface acoustic wave (SAW) filters fabricated in Vectron's US-based Hudson, New Hampshire and European, Neuchatel, Switzerland factories, respectively.
These are combined with a dedicated custom ASIC design to produce a very low RMS jitter performance of less than 0.25ps RMS across the 12kHz to 20MHz range (622.08MHz output frequency).
Output frequencies for the VS720 range from 300 to 800MHz, compared with 500 to 800MHz for the VS700, which is a first for a device this size.
The SAW-based oscillator features tight frequency stability over a wide operating temperature range.
Specifications include temperature stability of +/-20ppm typical and minimum APR of +/-50ppm over a -40 to +85C temperature range.
Initial accuracy is +/-25ppm typical at 25C for Vc of 1.65V.
Linear VXCO gain is approximately 75ppm/V.
Additional features include 3.3V operation and an enable/disable function on pin 2.
The VS720 is housed in a standard 5 x 7.5mm hermetically sealed leadless, surface mount package and complies with RoHS requirements for lead-free products.
