The addition first-hit tdcc makes TDC-GP22 suitable for high dynamic applications as ultrasonic water meters. This is done by measuring one and two periods of a reference oscillator.
Ideally this measurement and the following calculation is done by the TDC itself. Evaluation software package for GPX2 incl.
TDC-GP21 Features – Time to Digital Converters
gp221 The figure shows the principle of operation. General Description TDC-GP21 is a 2-channel TDC with additional analog elements like extended fire-pulse generator, zero-cross detection and analog switches for simplifying the use in ultrasonic flow meter applications.
This type of TDC uses the absolute propagation time of signals through simple logical elements for fine quantisation of time intervals.
In other words, it determines how many inverter cycles the measured time interval consists of. It drastically simplifies the design of ultrasonic heat and water meters and is the necessary step for compact energy-saving ultrasonic water meters.
Therefore the measured value must be calibrated.
The latest software can be downloaded here: Clever circuit set-ups, redundant elements and special layout methods on the chip enable the exact reconstruction of the number of basic time intervals. Ultrasonic heat meters Ultrasonic gas meters Ultrasonic flow indicators Laser rangefinders Magnetostrictive yp21.
For more information, please email sales gpta. The high resolution is all the more impressive as this TDC is realized on a radiation hard process. The propagation delay itself depends on temperature and supply voltage.
TDC-GP21 Libraries – EasyEDA
The resolution strictly depends upon fp21 basic delay time in the chip. Resolutions in the range of 14 ps can be achieved by a simple set-up of the measuring core and the use of a state-of-the art CMOS process. TDC-GP21 is tdv 2-channel TDC with additional analog elements like extended fire-pulse generator, zero-cross detection and analog switches for simplifying the use in ultrasonic flow meter applications.
On the base of the ATMD-System we also develop complete solutions and additional modules to fit your application. The TDC-GPF01 firmware does the linearization and temperature compensation based on spool piece specific calibration data and completes the system-on-chip approach.
This product suits for the following applications: For more information, please contact RoentDek. The wealth of experience acam has gathered assures the ability to integrate all necessary funtions on a single circuit and so to provide a system-on-chip solution.
