PCI-104 Carrier (SMT130), FPGA Module, Virtex-4 with a 1GHz ADC module (SMT381 + SMT368)
The SMT291 is made up of the SMT130 (A PCI104 single site TIM carrier) and a SMT391 (ADC Module; Dual Channel 1GHz, 8-bit ADC; Virtex-4; SX35; ZBT-SRAM ; SLB Interface; SHB Interface). This combination gives high performance in a compact form factor.
The SMT130 is a single site module carrier developed to provide access to a TIM module over the PCI-104 PCI bus.
Data transfers of 50-100Mbytes per second can be achieved to and from the Global Bus when accessing the SRAM and PCI Bridge, allowing fast data transfers.
The SMT391 is a single width TIM module. It is capable of sampling two analogue inputs at 1 GSPS with a resolution of 8 bits. An Atmel dual channel ADC (AT84AD001) performs the analogue to digital conversion.
Digital data is output to a Xilinx Virtex-4 SX-35 FPGA , which controls data transfers via ComPorts or the Sundance High-speed Bus (SHB). These interfaces are compatible with a wide range of Sundance processor and I/O modules.
An on-board prom can load the default configuration via the ComPorts into the FPGA at start up. The FPGA can be dynamically re-configured at any time. Configuration, sampling and transfer modes are set by configuration data received over the ComPorts.
The SMT391 is a ‘Daughter-Module’ that combines with the SMT368 Module and the interface between the SMT368 and the SMT391 is done using the Sundance Local Bus (SLB) and all the analogue circuits are on the top PCB and the digital circuits are on the bottom to reduce the cross-talk, provide better separation and heat-dissipation.
