The
Intel Mobile Module’s clocking architecture
supports the use of SDRAM. Due to the tight timing
requirements of 66-MHz SDRAM clocks, the clocking
mode for SDRAM or system manufacturer custom
memory configurations allows all host and SDRAM
clocks to be generated from the same physical
device on the system manufacturer I/O Module.
Driving all of these clocks out of a single device
ensures minimal skew and jitter between clock
outputs. For complete details about using SDRAM
memory, and for trace length guidelines, refer to the
Intel Mobile Module Design Guide
(Order Number
243339).
For details on memory device support, organization,
size and addressing, refer to 430TX PCIset
documentation and PCD application notes.

64-MBIT SDRAM SUPPORT
Support for 64-Mbit SDRAM memory technology is
provided
by
the
430TX
component. See the 430TX PCIset documentation
for operational details on how this support is
implemented by the component. To provide the
equivalent support at the Intel Mobile Module
connector and maintain compatibility with future
Northbridge architectures, the memory signals on the
Intel Mobile Module are routed to the connector as
shown in Figure 3.
PCIset
Northbridge
Memory control signals that allow the 430TX PCIset
to support 64-Mbit SDRAM memory devices are the
RAS4/MA12 and RAS5/MA13. These signals are
multiplexed and configurable within the 430TX
PCIset. Figure 3 shows a wiring diagram on the Intel
Mobile Module of the RAS4/MA12 and RAS5/MA13
signals for clarification. Proper routing of these
signals is required to ensure future Intel Mobile
Modules are compatible.
