Flying Wire Adapter
An adapter is provided for attachment to legacy target
systems that do not incorporate a shrouded male 2 mm
connector
flying wires for connection to distributed terminals on a
target system.
The adapter is a small circuit board with two connectors
(Figure
adapter mates with the 14-pin Platform Cable USB male
2 mm connector. A 7-pin right-angle header on the top
side of the adapter mates with the standard Xilinx flying
wire set (included).

Physical Connection to the Host
Each Platform Cable USB includes a detachable, Hi-Speed
certified 1.8 meter A-B cable
circumstances should user-supplied cables exceed 5 meters.
Sub-channel cables (intended for low-speed 1.5 Mb/s
signaling) should not be used with Platform Cable USB.
A standard series B receptacle is incorporated into the left
side of the case for mating with the detachable Hi-Speed A-B
cable. A separate chassis ground is attached to the A-B cable
drain wire and returns ESD current to the host system ground.

Target Interface Connectors
Mating connectors for attachment of the high-performance
ribbon cable to a target system are available in both
through-hole and surface mount configurations
Shrouded and/or keyed versions should always be used to
guarantee proper orientation when inserting the cable. The
connector requires only 0.162 in
The target system voltage applied to pin 2 of this connector
is used as a reference for the output buffers that drive the
TDI_DIN_MOSI, TCK_CCLK_SCK, and TMS_PROG_SS
pins.Table 3
connectors that are compatible with the Platform Cable
USB ribbon cable.
This method of connection is not recommended because it can
result in poor signal integrity. Additionally, damage can result if
the leads are unintentionally connected to high voltages.
One flying wire adapter with wires is supplied with the Platform
Cable USB. Additional flying wire adapters with wires can be
purchased separately (see
