The Universal Frequency-to-Digital Converter (UFDC-1) is a universal 2-channel high precision multifunctional converter based on novel frequency-time conversion methods. It is perfectly suited to any applications where frequency-time parameters but also sensors output signal, have to be measured with highest resolution and programmable accuracy during the non-redundant conversion time and self-adaptive possibilities. The UFDC-1 covers all specified converted range of frequencies and accuracy for modern frequency-time domain sensors.
The UFDC-1 is a complex fully digital CMOS integrated circuit (IC). By using this IC it is possible to build a wide variety of digital, smart sensors and intelligent sensor systems. The device achieves a high-resolution conversion for data acquisition systems designed to support all range of frequency-time domain and digital sensor applications. It offers high performance with flexibility and requires a minimum of external components. It can be easy included into digital environment, controlled by an external microcontroller or work independently as a separate measuring unit without an external control. The function selection can be configured in both software and hardware. The IC converts frequency-time domain signals into digital domain and provides interface to microcontroller, DAQ or sensor system to read these digital results.
The UFDC-1 can measure the following frequency-time parameters of signals:

The UFDC-1 and UFDC-1M-16 can also work with voltage and current output sensors. It this case, any voltage–to-frequency converter (VFC) can be used. The accuracy of such system will be determined by sensor accuracy as well as by VFC accuracy.

Main Differences Between the UFDC-1 and UFDC-1M-16
|Reference frequency, MHz||0.5||16|
|Frequency range||0.05 Hz ... 7.5 (120) MHz||1 Hz ... 7.5 (120) MHz|
|Conversion time*, s||0.0002 ... 0.2||0.00000625 ...0.00625|
* The conversion time is non-redundant and depends on the programmable relative error.
The custom design is available. The possibility additional functions include but not restricted by:
Additional measuring modes (for example, frequency (period) deviation; measuring mode with non-redundant reference frequency for low power applications, etc.)
Additional mathematical operations for on-chip data and signal processing
Increased accuracy, reduced conversion time and expanded frequency range
Integrating sensor interface ICs and precision data converters into your system
IEEE 1451 standard support
Extended temperature range
Most of necessary functions can be implemented on a single circuit and so to provide a system-on-chip solution. Both devices can also be supplied in wafer form. On the base of the UFDC-1 and UFDC-1M-16 we also can develop complete solutions and additional modules to fit your applications. For more information please contact: email@example.com
