Fast, Accurate Universal Frequency-to-Digital Converter for Quasi-Digital Sensors and Transducers

 

 

18 June 2007, Toronto, ON, Canada - SWP, Inc. has introduced its new model of fast, two-cannel Universal Frequency-to-Digital Converter UFDC-1M-16. This IC is designed for applications requiring high conversion speed. In comparison with the previously model of UFDC-1 the new converter has increased up to 16 MHz internal reference frequency and decreased in 32 times conversion speed.

 

The UFDC-1M-16 is based on patented advanced modified method of the dependent count for frequency-to-digital conversion. The IC has wide frequency range from 1 Hz to 7.5 MHz (120 MHz with prescaling), programmable relative error from 1 to 0.001 % at appropriate non-redundant conversion rate from 6.25 ms to 6.25 ms and three popular communication interfaces for sensors applications: I2C, SPI and RS-232. The fast conversion time makes the IC's speed comparable with successive-approximation and S-D ADCs.

 

The converter are suitable for any sensors, transducers and encoders with frequency, period, duty-cycle, PWM, phase-shift, pulse number output in order to convert informative parameters to digital. There are 16 measuring and one generating (8 MHz) modes. The UFDC-1M-16 can directly convert the following frequency-time parameters of signal:

  • Frequency

  • Period

  • Duty-cycle

  • Duty off factor

  • Time interval between start- and stop-pulse

  • Phase-shift

  • Pulse width and space

  • Frequencies and periods ratio

  • Frequencies and periods difference

  • Rotation speed

  • Event counting

The UFDC-1M-16 is available in 28-lead Plastic Dual Inline Package (PDIP), compact 32-lead TQFP package and in a wafer form for embedded applications.
