Sundance SMT351 - Manual (Page 7)

Introduction
Description
The SMT351 card is a TIM format memory module that is able to store up to 1GB of
data at 400MB/s.
The module works in a similar way than a FIFO memory. The first data stored into
module will be available in output.
SMT351 modules can be cascaded to extend storage capability.
The module is based on DDR SDRAM memory components running at up to 133
MHz. DDR (Double Data Rate) SDRAM activates the data outputs on both the rising
and falling edges of the system clock rather than on just the rising edge, potentially
doubling the output.
A Xilinx Virtex-II Pro FPGA (or XC2VP20, or XC2VP30) controls input and output
data flows on two Sundance High-speed Bus ( SHB ) connectors. This bus is
compatible with a wide range of Sundance processor, converter and I/O modules
