TTC Receiver

N.B.: DO NOT USE THE FIRMWARE ON THIS PAGE TO RECEIVE TTC SIGNALS FROM THE AMC13.

Use the one available here instead: AMC13BackplaneLink

This page documents a TTC receiver developed for the HCAL DTC (a MicroTCA MCH). This receiver is unique in that it does not use the official TTCrx ASIC from CERN, but instead commercial off-the-shelf (COTS) components.

Please see:

• my slides from Oct 2010 where I describe the scheme in some detail.
• Reference Design including schematic, UCF and VHDL files (rev 2011-07-29). Note: this code may still work, but has been integrated into a complete link including DAQ for AMC13 use. Please contact us if you need code to talk to your AMC13
• Older information:
  • Schematic Excerpts from AMC13 Module.
  • TTC_decoder.vhd preliminary VHDL code for receiving and decoding the TTC protocol, intended for use on an AMC module in a MicroTCA crate with DTC or AMC13 distributing TTC data on Fabric B. This code is out of date; contact us for more information.
