A.1.1 Exclusion Zone

It is recommended that you allow for an "exclusion zone" of 0.25" (6 mm) around the Coyote in all directions when the Coyote is incorporated into an assembly that includes other components. An "exclusion zone" of 0.12" (3 mm) is recommended below the Coyote. Figure A-2 shows this "exclusion zone."

Figure A-2. Coyote "Exclusion Zone"

A.1.2 Physical Mounting

Figure A-3 shows position information to assist with interfacing other boards with the Coyote.

A.2 Conformal Coating

The areas around the crystal oscillator and the battery backup circuit on the Coyote's RabbitCore module have had the Dow Corning silicone-based 1-2620 conformal coating applied. The conformally coated areas are shown in Figure A-4. The conformal coating protects these high-impedance circuits from the effects of moisture and contaminants over time, and helps to maintain the accuracy of the real-time clock.

Figure A-4. Coyote's RabbitCore Module Areas Receiving Conformal Coating

Any components in the conformally coated area may be replaced using standard soldering procedures for surface-mounted components. A new conformal coating should then be applied to offer continuing protection against the effects of moisture and contaminants.

NOTE	For more information on conformal coatings, refer to Technical Note 303, Conformal Coatings.

A.3 Jumper Configurations

Figure A-5 shows the header and jumper locations used to configure the various Coyote options.

Figure A-5. Location of Coyote Configurable Positions
(RabbitCore module is not shown)

Table A-2 lists the configuration options. 0 W surface mount resistors are used for all the positions except JP10 and J8, which use standard pluggable jumpers.
