CMCPCI102B
Application Information
Board Layout Recommendations
The CMCPCI102B devices should be located on the
board as close as possible to the CompactPCI connec-
tor. Whether a signal is terminated or not depends
upon application, as shown in the following table:
Figure 7
shows a 64-bit system board connection
between the CMCPCI102B termination and the Com-
pactPCI 5-row connector (2 mm pitch) labeled A to E
(row F is Ground). The System slot should have signal
lengths not exceeding 63.5 mm (2.5 inches). To mini-
mize trace length, it is recommended that the
CMCPCI102Bs be placed on alternate sides of the PC
board. The configuration shown illustrates a fully-termi-
nated 64-bit board utilizing 10 CMCPCI102B devices.
Some applications (e.g. 32-bit boards) do not require
all lines to be terminated, per the above table.
The CMCPCI102B resistors have a very low TCR
(
typ-
ically -100ppm/°C) so that resistance will not fluctuate
over temperature. Buffers are implemented on P_EN,
5_EN and 3_EN inputs to ensure that switches turn on
and off completely.
A typical system slot card may use 10 CMCPCI102B
devices to replace 10 10-bit FET bus switches and 76
4-resistor packs (0805 form factor), thus providing sig-
nificant reduction in both component count and assem-
bly costs. At the same time this highly integrated
solution improves reliability and manufacturing effi-
ciency, saves board area for space-critical designs,
and satisfies CompactPCI height requirements.
