Chapter 1: ML501 Evaluation Platform
R
2. DDR2 SODIMM
The ML501 platform is shipped with a single-rank unregistered 256 MB SODIMM. The
DDR2 SODIMM used is generally a Micron MT4HTF3264HY-53E or similar module. Serial
Presence Detect (SPD) using an IIC interface to the DDR DIMM is also supported with the
FPGA.
Note: The board is only tested for DDR2 SDRAM operation at a 400 MHz data rate. Faster data
rates might be possible but are not tested.
MIG Compliance
The ML50 x DDR2 interface is MIG pinout compliant. The MIG DDR2 routing guidelines
outlined in the Xilinx Memory Interface Generator (MIG) User Guide [Ref 13] have been
achieved.
The board’s DDR2 SODIMM memory interface is designed to the requirements defined by
the MIG User Guide using the MIG tool. The MIG documentation requires that designers
follow the MIG pinout and layout guidelines. The MIG tool generates and ensures that the
proper FPGA I/O pin selections are made in support of the board’s DDR2 interface. The
initial pin selection for the board was modified and then re-verified to meet the MIG
pinout requirements. To ensure a robust interface, the ML50 x DDR2 layout incorporates
matched trace lengths for data signals to the corresponding data strobe signal as defined in
the MIG user guide. See Appendix B, “References” for links to additional information
about MIG and Virtex-5 FPGAs in general.
DDR2 Memory Expansion
The DDR2 interface support user installation of SODIMM modules with more memory
since higher order address and chip select signals are also routed from the SODIMM to the
FPGA.
DDR2 Clock Signal
Two matched length pairs of DDR2 clock signals are broadcast from the FPGA to the
SODIMM. The FPGA design is responsible for driving both clock pairs with low skew. The
delay on the clock trace is designed to match the delay of the other DDR2 control signals.
DDR2 Signaling
All DDR2 SDRAM control signals are terminated through 47 Ω resistors to a 0.9V VTT
reference voltage. The FPGA DDR2 interface supports SSTL18 signaling and all DDR2
signals are controlled impedance. The DDR2 data, mask, and strobe signals are matched
length within byte groups. The ODT functionality of the SODIMM should be utilized.
3 . Differential Clock Input And Output With SMA Connectors
High-precision clock signals can be input to the FPGA using differential clock signals
brought in through 50 Ω SMA connectors. This allows an external function generator or
other clock source to drive the differential clock inputs that directly feed the global clock
input pins of the FPGA. The FPGA can be configured to present a 100 Ω termination
impedance.
