3.3.3 Clocks
The host board provides one SDRAM clock to the memory expansion connector. The frequency
of the RAM5500 CLKS is the same as the host board. This clock is used to generate the on-board
SDRAM clocks using a phase lock loop zero delay clock driver.
3.4 Memory Expansion Connector Pin Assignments
The P1 connector on the RAM5500 is a 140-pin AMP 4mm Free Height mating plug. This plug
includes common ground contacts that mate with standard AMP receptacle assemblies or AMP
GIGA assemblies with ground plates. Refer to
Memory Expansion Connector (P4) on page 107 for
the P4 pin assignments.
*Common GND pins mate to a GIGA assembly with a ground plate. The GIGA assembly is an
enhanced electrical performance receptacle and plug from AMP that includes receptacles
loaded with contacts for grounding circuits at 9 or 10 signal circuits. These ground contacts
mate with grounding plates on both sides of the plug assemblies.
