3.3.2Cable connector specifications

Table 3.2 lists the recommended specifications for the cable connectors for Host system that do not support Ultra DMA modes greater than mode 2.

For Host system that support Ultra DMA modes greater than mode 2, it is recommended to use the 80-conductor cable assembly. The 80-conductor cable assembly is manufactured by AMP or 3M.

	Table 3.2	Cable connector specifications
	Name		Model	Manufacturer
	Cable socket		FCN-707B040-AU/B	Fujitsu
ATA interface cable	(closed-end type)
(40-pin, CN1)	Cable socket		FCN-707B040-AU/O	Fujitsu
	(through-end type)
Power supply cable	Cable socket housing		1-480424-0	AMP
(CN1)	Contact		60617-4	AMP

Note :

The cable of twisted pairs and neighboring line separated individually is not allowed to use for the host interface cable. It is because that the location of signal lines in these cables is not fixed, and so the problem on the crosstalk among signal lines may occur.

It is recommended to use the ribbon cable for ATA interface that cable length is less than 18 inch (46 cm) and cable capacitance is less than 35 pico farad. Also it is recommended to use AWG18 power supply cable.
