7. For example connection to a video D/A converter, see CE2 schematic:
A EVMCE2-4_schematic.pdf, or later version.
8. iPod dock connector pin and GPIO assignments are under discussion. Please contact BridgeCo for
recommendations for iPod dock connections to CX870 module.
9. For example connection to an LCD display, see CE2 schematic:
A EVMCE2-4_schematic.pdf, or later version.
10. All the above signals are brought out to J2 pins. Not all the above signals are brought out to J3, the 64-pin low
density connector. The J3 pin assignments table shows which signals are brought out to the J3 pins.
11. BridgeCo has a set of example motherboard schematics that shows example external circuitry that is typically
connected to the module. Please check the BridgeCo customer portal for a copy of these example schematics.
12. Please check the BridgeCo Customer Portal Download area for the latest version of the BridgeCo documents.
