To secure margin against EMI of around 400 MHz,
route the LVDS harness using the following
procedure:
procedure:
1. Route the LVDS connector upward from the exit of the
D block, and secure it on the side of the shield upper
cover of the D block with conductive tape.(Fig.1)
cover of the D block with conductive tape.(Fig.1)
2. Secure the tape (white) portion bundling the LVDS
harness to the corner of the DIC shield upper cover of the
D block with conductive tape, and bend the harness as
shown in Fig. 1.(Fig.2)
D block with conductive tape, and bend the harness as
shown in Fig. 1.(Fig.2)
3. Route the LVDS harness through the slot on the DIC and
ATSC and secure it with conductive tape.(Fig.2)
4. Secure the LVDS harness under the drop-safe part; as a
guide, attach tape on the side edge of the shield upper
cover.(Fig.3)

5. Secure the LVDS harness upward near the shield clamper
of the D block with conductive tape; as a guide, attach
tape above the connector on the chassis of the D block.

6. Route the LVDS harness through the clamper, and secure
it with conductive tape so that it is held on the top in the
clamper.(Fig.4)

Note :
1.Ensure that the LVDS harness has no slack in steps 1

through 6.
2.When attaching the drop-safe part, be careful not to
entangle it in the portions of LVDS harness described in
steps 3 and 4.
steps 3 and 4.
The drop-safe part needs to be removed before the
above procedure.
The size of each conductive tape should be 19 mm x 40
mm, which is the same size as 4-101-007-01 attached on
the exit of the LVDS connector.
