Hardware Design Considerations
3.3
Clock and Timing Signal Board Layout Considerations
When laying out the system board, use the following guidelines:
?
?
Note:
3.4
Note:
Keep clock and timing signal paths as short as possible and route with 50 Ω impedance.
Use a serial termination resistor placed close to the clock buffer to minimize signal reflection. Use the following
equation to compute the resistor value:
Rterm = Rim – Rbuf
where Rim = trace characteristic impedance
Rbuf = clock buffer internal impedance.
See MSC8144 CLKIN and PCI_CLK_IN Board Layout (AN3440) for an example layout.
Connectivity Guidelines
Although the package actually uses a ball grid array, the more conventional term pin is used to denote signal
connections in this discussion.
First, select the pin multiplexing mode to allocate the required I/O signals. Then use the guidelines presented in the following
subsections for board design and connections. The following conventions are used in describing the connectivity requirements:
1.
2.
3.
4.
5.
Note:
3.4.1
GND indicates using a 10 k Ω pull-down resistor (recommended) or a direct connection to the ground plane. Direct
connections to the ground plane may yield DC current up to 50mA through the I/O supply that adds to overall power
consumption.
V DD indicates using a 10 k Ω pull-up resistor (recommended) or a direct connection to the appropriate power supply.
Direct connections to the supply may yield DC current up to 50mA through the I/O supply that adds to overall power
consumption.
Mandatory use of a pull-up or pull-down resistor it is clearly indicated as “pull-up/pull-down”.
NC indicates “not connected” and means do not connect anything to the pin.
The phrase “in use” indicates a typical pin connection for the required function.
Please see recommendations #1 and #2 as mandatory pull-down or pull-up connection for unused pins in case of
subset interface connection.
DDR Memory Related Pins
This section discusses the various scenarios that can be used with DDR1 and DDR2 memory.
Note:
For information about unused differential/non-differential pins in DDR1/DDR2 modes (that is, unused negative lines
of strobes in DDR1), please refer to Table 51 .
