This Universal Frequency-to-Digital Converter (UFDC-1) is a fully digital CMOS integrated circuit for use with any sensor or transducer with a frequency, period, duty-cycle, interval, PWM , phase shift or pulse number output. The UFDC-1 is perfectly suited to any applications where frequency-time parameters or sensors output signals need to be measured with highest resolution and programmable accuracy. Non-redundant conversion time. The design is based on novel advanced methods for frequency, period, duty-cycle and phase-shift measurements. By using this IC it is possible to build a variety of digital frequency or counter instruments, smart sensors and intelligent sensor systems.
The UFDC-1 can easily integrate into digital environments with a minimum of external components. The UFDC-1 can be controlled by an external microprocessor (slave mode) or work independently without an external controller (master mode). The modes's can be configured in both software and hardware.
There are four variant ICs: UFDC-1, UFDC-1M-16, USTI and USTI-EXT . The UFDC-1M-16 has a 32 times increased conversion speed over the UFDC-1.
• 2 channels for frequency (time) to digital conversion.
• 16 Measuring modes.
• 1 Frequency generating mode 8Mhz.
• RS232, RS485, SPI (3-wire) and I2C Interface.
• Measuring modes, relative error and accuracy programmable.
• Programmable accuracy (relative error) for frequency (period) conversion from 1 % to 0.001%.
• Scalable resolution.
• UFDC-1 Frequency range 0.05 Hz to 7.5 MHz (120 MHz with pre-scaling).
• UFDC-1 Conversion time 0.0002s to 0.2 sec.
• UFDC-1 Internal 500 kHz (0.5 MHz) with a 16MHz quartz oscillator.
