The TAPR TICC is a two-channel timestamping counter with better than 60 picosecond resolution and less than 100 picosecond typical jitter. It has an Allan Deviation noise floor below 1x10-10 for a one second measurement.
The TICC designed to measure low-rate time intervals, such as the pulse-per-second signal from a clock or GPS, with very high resolution. The TICC hardware is a "shield" that mounts on an Arduino Mega 2560 processor board, and the TICC software runs on the Arduino. Data is sent via USB to a host computer for logging and analysis. The TICC can currently perform over 100 measurements per second; we believe that software optimization will ultimately increase the measurement speed.
The TICC can output timestamp data for each channel, or the time interval between the two channels. The channel inputs trigger with about 1.7 V and are safe to 5 V. Input impedance is 1 megohm. The TICC requires an external 10 MHz reference clock at nominally +3 dBm, though the input circuit operates over a wide amplitude range.
The TICC is powered by the Arduino to which is is attached, which in turn can be powered by the USB cable from the host computer.
More information about the TICC is available at febo.com/pages/TICC.
The TICC software is open source and available from github.com/TAPR/TICC. The git repository also includes data sheets and other information on some of the hardware components. The software is undergoing active development.
(Note that the photo above is of a prototype board. The production boards will be very similar, but will use standard headers to mount to the Arduino, rather than the stacking headers shown.)
AvailabilityTAPR is planning a production run of fully assembled and tested TICC systems. We have already placed an order with our contract manufacturer. This represents a significant up-front cash outlay for the organization, so we are encouraging you to place orders early. As an incentive, we are we are offering a $10 discount ($180 rather than $190 each) for orders placed on or before December 21, 2016.
(Note: the $10 discount for orders placed on or before December 21st will be applied manually during order processing and therefore won't be shown during the web site checkout process)
The TICC system will include the TICC shield and an Arduino 2560 Mega compatible board with TICC software loaded. The systems will be tested for functionality prior to delivery.
Delivery from our contract manufacturer to TAPR is expected in early February, 2017, and we will ship to customers as quickly as we can after receipt.
The price for the TICC w/Arduino is:
$ 190 US for members of TAPR
$ 190 US for non-members+ shipping/handling if applicable.

ALSO There is a problem with Chrome inaccurately reporting that the connection is insecure when you are attempting to complete your order. We suggest using a different browser to place the order.
Both problems are being worked on, sorry for the inconvenience.
Shipping and Handling
Shipping and Handling within the US will be by USPS Priority Mail.
International shipping costs are calculated as closely as possible. If the actual cost exceeds the estimate by more than $10.00, TAPR will contact you to get approval for the additional funds. TAPR uses insured Priority Mail International, unless the purchaser requires something else.
The operating manual can be found online at http://www.tapr.org/~n8ur/TICC_Manual.pdf.
The TAPR TICC was made possible by the efforts of:
John Ackermann, N8UR – Hardware and software designer, and Project Manager
George Byrkit, K9TRV – Software development and hardware tester
Jeremy McDermond, NH6Z – Software development
Tom Van Baak – Beta tester
