CTR FMC 5-channel Digital I/O module for Central Timing
The CTR FMC card that can be used, in conjunction with the Simple PCIe FMC carrier - SPEC or with the uMTCA carrier ctr-amc to design a General Machine Timing Receiver - GMT
The goal is to have a replacement of the CTRI GMT PCI receiver, with identical functionality.
Functional specifications
- Low-pin count FMC form factor
- FMC Vadj 2.5V or 3.3V
- 2 input ports
- Central timing (lemo 00 2-pin, RS485 level)
- eXternal start input (TTL level)
- 3 outpus ports, fixed (Lemo 00 connectors. 5V TTL level)
- The board may be produced to have 4 outputs, loosing the eXternal start input
- 40 MHz DAC-adjustable clock oscillator for GMT PLL and 44 MHz oscillator for the PLL uncorrelated clock
- 6 LED's on front Panel : PLL LOCKED, OUTPUTS, GMT OK
- Signal level,
- 4-layer PCB

Date | Event |
---|---|
09.08.2017 | First discussion about need for CTRI replacement (low stock, obsolete components) |
05.12.2017 | Decided at section meeting that we need to keep 4 outputs on the new card and reduce the inputs to just 1 - the GMT input. This is due to only 7 out of the 243 CTRI cards installed using the other 2 inputs. Note: final produced version EDA-03801-V2-0 has 3 outputs and 2 inputs: external start and GMT (EB, 19.02.2021) |
12.02.2018 | Keith : Schematic of the new CTR FMC card has been completed and is ready to be verified by another engineer. |
14.02.2018 | Review by Tom Wlostowski (see internal WIKI page) |
28.02.2018 | Schematics review by Denia , Erik and Dimitris |
26.03.2018 | PCB layout done by Maxime Ricci of the DEM group |
29.03.2018 | PCB review by Erik, Denia, Keith and Magnus Bjork. Agreed some changes to the layout. |
04.04.2018 | Keith and William (design office) made changes to PCB layout. |
27.06.2018 | DEM will change the schematics to a version 2. The front panel text will change slightly - LED numbering. OSC 1 will be mounted now and OSC 2 unmounted due to component availability. |
25.08.2018 | 7 prototypes were programmed and tested by the end user successfully |
09.09.2018 | All components have now been delivered to the DEM team and 750 blank PCB's have been ordered. company to mount the boards. |
27.09.2018 | We will make another 50 prototypes to test before tendering the whole order of 750 externally. |
20.12.2018 | 54 cards were mounted onto SPECS and the new combined card (CTRIE) programmed and tested in new Siemens front-ends successfully. |
22.01.2019 | 700 more CTR-FMC cards were ordered. |
12.04.2019 | 700 CTR-FMC cards delivered and have been tested since. |
