.. _svec_ref_tdc_x2:

SVEC-based TDC x 2
==================

This is a WRTD :ref:`node` based on the `Simple VME FMC Carrier (SVEC)
<https://www.ohwr.org/project/svec/wikis/home>`_ and the `FMC Time to Digital Converter (FMC-TDC)
<https://www.ohwr.org/project/fmc-tdc/wikis/home>`_.

The basic principle of this :ref:`node` is simple: it takes in
external pulses on its FMC-TDC inputs, timestamps them using WR time
and converts them to WRTD :ref:`Messages <message>`, to be sent over
the WR network.

Architecture and performances are similar to :ref:`svec_ref_tdc_fd`.
The node has 10 :ref:`Local Input Channels <local_channel>`, they are mapped
to the five inputs of each FMC-TDC.
