Internal connections
CB6464 24 Version: 0.4
7.2 Internal: BAseCon140 (Q170 only)
In conjunction with the Q170 chipset, the BAseCon140 connector enables the flexible extension of the IO
functions of the CB6464. It provides up to eight PCIe lanes, of which a maximum of four can be multiplexed
with SATA 2.0 (3G) and a maximum of four with PCIe lines, as well as a maximum of four PCIe lines with a
maximum of four USB 3.0 lines (see table). In addition, DisplayPort, SSIC, SMBus and 1Wire signals are led
out via the BAseCon connector. The expansion board takes care of the configuration of the IO functions. A
PIC on the expansion card contains the configuration data that are communicated to the board upon
connection, thus enabling an uncomplicated and self-configuring extension to the IO options.
With Q170 only
Max. 4x SATA Gen 3 / max. 4x PCIe x1 Gen 3
(multiplexed) Total: 8x PCIe x1
(configurable – see left)
Max. 4x USB 3.0 / max. 4x PCIe x1 Gen 3
(multiplexed)
1x DisplayPort 1.4 / HDMI 2.0
Observe the current limits!
In order to avoid damaging the device, it is essential to observe the following current limits:
A maximum load of 2.8 A per pin must not be exceeded. On account of the different current con-
sumptions of the usable processors the actual current consumption may be lower. The respective
maximum values can be obtained from your distributor on inquiry.
Irrespective of the CPU in use, a maximum total load of 100 W must not be exceeded.
NOTE
Mirrored Signal at BAseCon-plug Stack Down
At the Stack Down version of the BAseCon plug (plug on the bottom-side of the board), the signals are
transferred by a stack to the mating plug. On this mating plug (Stack Up) the signals are mirrored. On the
stack itself there is no mirroring.
