UG347 (v3.1.1) October 7, 2009

Detailed Description

R

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.

A differential clock output from the FPGA is driven out through an LVDS clock 
multiplexer (U12) onto a second pair of SMA connectors (J12 and J13). This allows the 
FPGA to drive a precision clock to an external device such as a piece of test equipment. 

Table 1-3

 summarizes the differential SMA clock pin connections.

4. Oscillators

The board has one crystal oscillator socket (X1) wired for standard LVTTL-type oscillators. 
It connects to the FPGA clock pin as shown in 

Table 1-4, page 20

. The X1 socket is 

populated with a 100-MHz oscillator and is powered by the 3.3V supply.

The board also provides an IDT5V9885 (U8) EEPROM programmable clock generator 
device. This device is used to generate a variety of clocks to the board peripherals and

Notes: 

1. When jumper J54 (located near the battery) is not shunted (default), the FPGA differential clock output 

is selected on U12 and driven out to the SMA connectors, J12 and J13.
