12-18 Schematics, Board Layouts, and Parts Lists: VOCON Board

Figure 12-12. NCN6186_ VOCON Board Overall Circuit Schematic—Sheet 2 of 2

Notes: This design supports both Patriot Ram 2.2 and Patriot Bravo. Jumpers in the "Controller & Memory" block need to be changed depending on the device to be used.

Block descriptions:

ESD SPARK GAPS - Contains non-physical parts representing spark gap layout features for ESD protection.

UNIVERSAL CONNECTOR BLOCK - Filtering and signal shaping for Control top / universal connercor. Transmit LED Circuit.

ASIC BLOCK - RS232 level conversion, USB Tranceiver, UCM keyload data routing and Flipper Asic..

CONTROLLER AND MEMORY BLOCK - Patriot u-controller, Memory devices and DC_CLOCKs sub-block.

DC_CLOCKS SUB-BLOCK - 1.55 V regulator, 16.8 MHz clock buffer and smart battery circuitry.

RF AND DISPLAY INTERFACE - Display circuits and filtering/signal shaping for the 26 pin RF - VOCON interface.

AUDIO AND DC BLOCK - GCAP IC (power control, voltage regulators, codec, AD converters), audio PA, and 5 volt regulator.
