Review: Abracon MEMSpeed Pro II Programmer / MEMS Oscillators

March 29, 2013 by Sebastian Westerhold 2 Comments
Using the harmonic marker function of the Teledyne LeCroy HDO4025 12-bit high definition oscilloscope to view the harmonic content of the output signal

Most circuit design engineers know this problem. They seem to have an inexhaustible amount of oscillators with all kinds of frequencies available, but there’s always one frequency that seems to be unavailable: the one they need. Abracon offers a variety of low-cost MEMS oscillators that can be programmed for a wide range of frequencies. When … [Read more…]

DSSS / BPSK Clock Recovery with the Abracon ABFT

November 5, 2012 by Sebastian Westerhold Leave a Comment
This is what the quick and dirty test setup looked like

Clock recovery in Spread Spectrum applications and BPSK modulated signals can be somewhat tricky. There are no commercial solutions available solely for this task either. Or are there? This article shows a great off-label use of the Abracon ABFT. Clock recovery in a Direct Sequence Spread Spectrum (DSSS) receiver can be quite a challenge. Because … [Read more…]

Review: Abracon ABFT Frequency Translators

November 4, 2012 by Sebastian Westerhold 1 Comment
Simple frequency doubler using a classic PLL based approach

In March, 2012, Abracon announced the production of ultra-low jitter, VCXO based frequency translators / jitter attenuators. This is supposed to resolve some problems that accompany classic PLL-based designs at an affordable price. Now, the ABFT frequency translators / jitter attenuators are available on the market and it’s time to have a closer look. The … [Read more…]

Review: Abracon ABPSM-ULN-A – Precision Power Supply Module

September 30, 2012 by Sebastian Westerhold 2 Comments
Noise density of the ABPSM-ULN-A

When bench testing noise sensitive circuits, one needs an ultra clean power source. Low noise lab power supplies are usually bulky and expensive. Abracon challenges both the bulkiness and the expensiveness with their new low noise pocket sized ABPSM-ULN-A ultra low noise power supply module. With the ABPSM-ULN-A, Abracon intends to set a new standard … [Read more…]

Review: Abracon Sync’n Go – Portable Precision Frequency Reference

September 26, 2012 by Sebastian Westerhold 1 Comment
Top: Output signal, Bottom: FFT of the output signal. Clearly visible is the 10 MHz peak on the left. The tiny humps to the right are present even if no signal is connected to the scope and therefore to be assumed noise of the scope itself.

Most professional devices which require high accuracy and precision have an input for some sort of external frequency reference. The frequency 10 MHz is an industry standard particularly for test equipment. Most reference generators are designed for lab use and therefore are bulky and unsuitable for portable use. Abracon now offers a pocket-sized portable solution. … [Read more…]

AOCJY1 series high stability OCXOs from Abracon

September 10, 2012 by Sebastian Westerhold 3 Comments
Output of the buffer amplifier measured on a LeCroy WaveAce 1002 and a x10 probe

An Oven Controlled Crystal Oscillator (OCXO) is used wherever one needs a highly accurate and precise frequency reference. Abracon manufactures a series of affordable off-the-shelf OCXOs, which are due to their low price and outstanding performance particularly suitable for homebrew designs. Abracon’s AOCJY1 series offers various through-hole OCXOs with several possible frequencies between 10 MHz … [Read more…]
