FMC ADC 100M 14b 4cha
The FmcAdc100M14b4cha is a 4 channel 100MSPS 14 bit ADC card in FMC (FPGA Mezzanine Card) format. By default it uses only signals from the LPC rows of the HPC connector that is mounted. The gain can be set by software in three steps: +/-50mV, +/-0.5V, +/-5V. An advanced offset circuit is used in the front-end design of the ADC board, and allows a voltage shift in the range of +/-5V that is independent on the chosen gain range.

03-11-2011: FMC ADC in company's catalog
The FMC ADC 100M 14b 4cha FMC card designed at CERN is available as a product in the catalog of the Dutch company INCAA Computers. It is the first CERN Open Hardware product that is available this way.
10-10-2011: Feedback from fabricator improves design
INCAA, the company who will make the first series production of the ADC card, reviewed the design before production. They found a problem in the schematics (the 6 Volt rail could be 6.2 Volt) and raised an issue about the PCB layout (thermal brakes too large). These issues were handled and also some minor improvements that we had still had in the Issues list are now included in the V5 design. INCAA will produce 40 of those boards for delivery in early January 2012.
20-09-2011: Production of 40 cards starts
After a succesful price enquiry, CERN has decided to use the company
INCAA Computers in The Netherlands to
produce 40 FMC ADC cards. They will be delivered in January 2012. CERN
needs to finalise the production test software still before shipping a
test bench to INCAA.
This card is the second CERN Open Hardware product that will be produced
in quantity by industry. The first one was the SPEC FMC
carrier that is being produced
by Seven Solutions from Spain.
Note that according to the CERN Open Hardware
Licence any company may
produce these designs.
