Block Descriptions  
This section describes the major blocks of the ML361 board.  
FPGA  
The ML361 uses a Xilinx XC2VP20FF1152C-6 Virtex-II Pro device. This device is packaged  
in a 1152-pin BGA package with a -6 speed grade. Refer to Appendix B, “FPGA Pinout,”for  
a complete pinout of the Virtex-II Pro device.  
Memories  
The ML361 board supports two types of memories: DDR SDRAM DIMM and DDR  
SDRAM.  
DDR SDRAM DIMM (Banks 6 and 7)  
The DDR SDRAM DIMM used on the ML361 board is a 184-pin, 200 MHz, unbuffered,  
non-ECC Micron MT4VDDT1664-AG-40BC3 device. This DIMM module has a 64-bit wide  
data interface. The board also has provisions to interface to a 72-bit wide DIMM.  
DDR SDRAM Components (Banks 2 and 3)  
The ML361 board contains five 200 MHz DDR SDRAM components that provide a 72-bit  
interface. These devices include four 16-bit Micron MT46V16M16TG-5B devices and one  
MT46V32M8TG-5B DDR SDRAM devices. They are packaged in 66-pin TSOP packages.  
They share a common address and control bus and have separate clocks and DQS/DQ  
signals.  
DDR SDRAM Component (Bank 1)  
The ML361 board contains one 8-bit Micron MT46V32M8TG-5B device on the top bank of  
the FPGA.  
RS232  
The ML361 board provides an RS232 serial interface using a Texas Instruments  
MAX3221CDBR device. The maximum speed of this device is 250 Kb/s. The RS232  
interface is accessible through a female DB9 RA connector.  
Clocks  
The ML361 board contains 166 MHz and 200 MHz LVDS clock oscillators and connectors  
for external LVDS clock inputs.  
200 MHz LVDS Clock  
The LVDS clock is a Pletronics LV1145BW-200.0M oscillator with a differential output. The  
oscillator runs at 200 MHz ± 50 PPM with an operating voltage of 2.5 V ± 5%. It is  
terminated at the FPGA with a 100Ω resistor. FPGA pins J17 and H17 in Bank 1 serve as the  
CLK_200_LVDSP and CLK_200_LVDSN inputs, respectively.

166 MHz LVDS Test Clock  
The LVDS test clock is a Pletronics SM7745DW-100.0M clock oscillator with a single-ended  
output. This oscillator runs at 166 MHz ± 50 PPM with an operating voltage of 2.5 V ± 5%.  
FPGA pins E17 and D17 in Bank 1 serve as the CLK_166_LVDSP and CLK_166_LVDSN  
inputs, respectively.  
SMA Clock  
Two SMA connectors are provided for the input of an off-board differential clock. The  
traces from the SMAs are run as a pair to the FPGA where they are terminated with a  
100 ohm resistor. AK18 serves as the CLK_SMAP input, and AL18 serves as the  
CLK_SMAN input for the SMA connector pair.  
User I/Os  
This subsection describes the devices that connect to the User I/Os of the ML361 board.  
Mictor Connectors  
The FPGA interfaces to two 38-pin Mictor connectors. They can be used to hook up to a  
logic analyzer. All signals from the FPGA to the connectors are matched closely. Refer to  
the Xilinx data sheets in Appendix A, “Related Documentation,” for more information.  
GPIO  
The ML361 board contains 16 general-purpose I/Os (GPIOs), which are accessible through  
two 2 x 8 0.100" pin headers (see Table 2-1 and Table 2-2). The even-numbered pins on each  
header are connected to ground. The GPIO header pins can be accessed through I/Os in  
Bank 0.

Terminations and Transmission Lines for DDR Components  
Data and Clock Signals (DQ, DQS, DM, CLK)  
For these DDR signals, the terminations at the FPGA and memory consist of a 50Ω parallel  
termination pulled up to 1.3 V.  
Use 50Ω transmission lines with less than ± 1% tolerance on the transmission line  
impedance. The recommendations for the transmission line lengths are as follows:  
All these data and clock signals are point-to-point from the FPGA to each DDR  
component. All signals going to one individual DDR SDRAM component need to be  
matched with respect to each other with a ± 2% tolerance.  
All signals going to the first component are matched to a trace length of 2.8 inches  
with a ± 2% tolerance. The 2.5 inch requirement includes the FPGA internal package  
skew (available on the pinout table) and the skew between the ball of the FPGA to the  
resistor pack as well as the length of the actual trace.  
The trace length variation on these signals across the five DDR components is kept as  
small as possible to enable data capture while also ensuring they fall within the  
address window. The trace lengths on all five DDR components are: 2.8 inches, 2.8  
inches, 3.5 inches, 3.8 inches, and 3.8 inches. All signals corresponding to the same  
DDR component are matched as close as ± 1% of the above mentioned trace lengths.  
Microstrip is used to model the transmission lines in the IBIS simulations.  
Address and Control Signals (A, BA, RASn, CASn, WEn, CSn, CKE)  
For the address and control signals, no termination is required at the FPGA. At memory, a  
50Ω resistor pulled up to 1.3 V at the end of the daisy chain is required (after the last DDR  
component).  
Use 50Ω transmission lines with ± 5% tolerance from the FPGA to all the memory  
components. The recommendations for the transmission line lengths are as follows:  
All the signals are routed in a daisy chain fashion.  
There is a maximum of 2.5 inch trace with ± 2% tolerance from the FPGA to the first  
DDR component. The 2.5 inch requirement includes the FPGA internal package skew  
(that is available on the pinout table) and the skew between the ball of the FPGA to  
the resistor pack as well as the length of the actual trace.  
0.6 inches of distance with ± 2% tolerance is used in the trace length calculations  
below between the individual components. Ideally, straight line routing is desired.  
During placement, the components are placed as close as 0.5 inches or lesser by  
straight line routing, if possible. The main requirement is that all signals going to each  
DDR component must be matched by ± 2% tolerance.

Duty Cycle Summary  
There is a total of 4.9 inches of trace from the FPGA to the last component assuming  
the DDR memory components are 0.6 inch apart.  
Microstrip is used to model the transmission lines for the first DDR component. All other  
DDR components use Buried Microstrip to model the transmission lines.  
Terminations and Transmission Lines for the DIMM  
Data and Clock Signals (DQ, DQS, DM, CLK)  
For these DIMM signals, the terminations at the FPGA and memory consist of a 50Ω  
parallel termination pulled up to 1.3 V.  
50Ω transmission lines are used with less than ± 1% tolerance on the transmission line  
impedance. The transmission line lengths are as follows:  
There is a 65 mm trace length from FPGA to memory with ± 0.5 mm tolerance.  
A maximum of 1 inch tolerance is allowed to include the FPGA internal package skew  
and the skew between the ball of the FPGA to the resistor pack. Package deskew is  
necessary if the 1 inch tolerance is not met.  
Address and Control Signals (A, BA, RASn, CASn, WEn, CSn, CKE)  
For the address and control signals, no termination is required at the FPGA or DIMM.  
Use 50Ω transmission lines with less than ± 5% tolerance on the transmission line  
impedance. The recommendations for the transmission line lengths are as follows:  
There must be a 65 mm trace length from FPGA to memory with ± 5 mm tolerance.  
Use a maximum of 1 inch tolerance to include the FPGA internal package skew and  
the skew between the ball of the FPGA to the resistor pack. Package deskew is  
necessary if the 1 inch tolerance is not met.
