Figure 13: High-Performance Ribbon Cable
Notes:
1. Ribbon Cable: 14 conductor, 1.0 mm center, round conductor flat
cable, 28 AWG (7 x 36) stranded conductors, gray PVC with pin 1
edge marked.
2. 2 mm ribbon female polarized connector, IDC connection to
ribbon. Contacts are beryllium copper plated, 30 micro-inches
gold plating over 50 micro-inches nickel. The connectors mate to
0.5 mm square posts on 2 mm centers.
3. One ribbon cable is supplied with the Platform Cable USB.
Additional ribbon cables can be purchased separately (see
"Ordering Information," page 20).
Flying Wire Adapter
An adapter is provided for attachment to legacy target
systems that do not incorporate a shrouded male 2 mm
connector (Figure 14). The adapter makes it possible to use
flying wires for connection to distributed terminals on a
target system.
The adapter is a small circuit board with two connectors
(Figure 15). The connector on the bottom side of the
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).

X-Ref Target - Figure 15
Notes:
1. 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.
2. One flying wire adapter with wires is supplied with the Platform
Cable USB. Additional flying wire adapters with wires can be
purchased separately (see "Ordering Information," page 20).
Physical Connection to the Host
Each Platform Cable USB includes a detachable, Hi-Speed
certified 1.8 meter A-B cable (Figure 16). Under no
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 (Figure 17).
Shrouded and/or keyed versions should always be used to
guarantee proper orientation when inserting the cable. The
connector requires only 0.162 in² of board space.
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 provides some third-party sources for mating
connectors that are compatible with the Platform Cable
USB ribbon cable.
