# VXS DSP FMC Carrier
|
|
|
|
|
|
## Project description
|
|
|
|
|
|
The VXS DSP FMC Carrier is an FMC carrier that can hold two FMC cards.
|
|
|
The FMC mezzanine slot uses a high-pin count connector (as opposed to
|
|
|
the OHR developments [Simple PCIe FMC
|
|
|
carrier](https://www.ohwr.org/project/spec/), [FMC PCIe Carrier
|
|
|
(PFC)](https://www.ohwr.org/project/fmc-pci-carrier) and the [VME FMC
|
|
|
carrier](https://www.ohwr.org/project/fmc-vme-carrier).
|
|
|
|
|
|
This board is optimised for the functionality required by RF
|
|
|
applications and will be usable with most of the FMC cards designed
|
|
|
within the OHR project (e.g. ADC cards, Fine Delay).
|
|
|
|
|
|
Other FMC projects and the FMC standard are described in [FMC
|
|
|
Projects](https://www.ohwr.org/project/fmc-projects).

## Main Features
|
|
|
|
|
|
*to be revised**
|
|
|
|
|
|
- 2 Spartan6 FPGA
|
|
|
o One dedicated to system tasks (S-FPGA)
|
|
|
o One fully available for the user applications (A-FPGA)
|
|
|
- 1 Analog Devices Sharc DSP
|
|
|
- 2 HPC (High Pin Count) FMC slots
|
|
|
- 40 user defined single ended (20 LVDS) connections from the A-FPGA
|
|
|
to P2 available for rear plug-in units (transition modules)
|
|
|
- flexible clocking resources
|
|
|
o 1 Voltage Controlled Temperature Compensated Crystal Oscillator
|
|
|
(VCTCXO)
|
|
|
o 1 any rate I2C programmable crystal oscillator
|
|
|
o 1 Direct Digital Synthesizer (DDS)
|
|
|
o 3 Phase Locked Loop (PLL) chips for clock cleaning and
|
|
|
redistribution to the FPGAs and the pluggable modules
|
|
|
- Large amount of on board memory
|
|
|
o 2 completely independent 72Mbit ZBT SRAMS
|
|
|
o A 2Gbit DDR3
|
|
|
o 2 SPI 128Mbit flash proms for multiboot S-FPGA powerup
|
|
|
configuration, storage of the A-FPGA firmware or of critical data
|
|
|
- Front panel connectivity
|
|
|
o 2 Small Formfactor Pluggable (SFP)
|
|
|
o 4 lemos configurable in all possible input/output combinations
|
|
|
o 1 e-SATA (to be confirmed)
