The OEM719 and OEM729 are discussed below.

Physical changes

Two of the OEM7 receivers are form factor replacements for OEM6 receivers. The OEM719 replaces the OEM615 and the OEM729 replaces the OEM628. Form factor replacement means that the OEM7 receivers:

• have the same physical dimensions as the OEM6 receivers

• have the same keep-out zones as the OEM6 receivers

• use the same locations for the mounting holes as the OEM6 receivers

• use the same connectors as the OEM6 receivers

• use the same locations for the connectors as the OEM6 receivers

The physical differences between the OEM7 and OEM6 receivers are described in the following sections.

Shielding

The OEM719 and OEM729 have an additional shield compared to the OEM615 and OEM628. However, all of the shields on the OEM719 are within the keep-out zone defined for the OEM615 and all of the shields on the OEM729 are within the keep-out zone defined for the OEM628. Designs that respected the keep-out zones for the OEM6 receivers will not be affected by the shields on the OEM719 and OEM729.

For information about the OEM615 and OEM628 keep-out zones, see the OEM6 Family Installation and Operation User Manual (OM-20000128). For information about the OEM719 and OEM729, see Figure: OEM719 Keep-outs and Figure: OEM729 Keep-outs.

Mounting

The OEM719 and OEM729 can be mounted using standoffs or bosses that have the same spacing required for OEM6 receivers. See Figure: OEM719 Dimensions and Figure: OEM729 Dimensions for the exact spacing.

OEM7 receivers also have an area on the edge of the cards to allow the use of mounting rails. In Figure: OEM719 Mounting Surface and Figure: OEM729 Mounting Surfaces, this is the area outside of the keep-out zone. On the OEM719, this area is 1.75 mm wide. On the OEM729, this area is 2.5 mm wide.

Using rails to mount the OEM7 receiver improves the thermal and vibration performance of the receiver. Securing the OEM7 receiver to mounting rails using clamping bars provides the most secure configuration for aggressive thermal and vibration use cases.

For more details about mounting OEM7 receiver cards, refer to the OEM7 Receiver Card Mechanical Integration Application Note (D19021).

The OEM7 receivers are slightly heavier than the OEM6 receivers they replace.
