9 / 15 page Arizona Microtek, Inc. AZPB70 Programmer Board for AZT70/71 www.azmicrotek.com +1-480-962-5881 9 Request a Sample May 2012, Rev 1.2 Figure 10 - AZT70 Capacitance Value Mapping AZT70/71 FUNCTIONAL MODES The AZT70/71 is designed to be used in 2 functional modes, Programming and Operational. In the Programming mode, the AZT70/71 is used by the manufacturer to set the capacitance value to control the desired center frequency of the oscillator. The programming mode uses either the shift registers or EEPROM (detailed later) and gives the manufacturer access to pins DA, CLK, and PV which allow the AZT70/71 to be programmed with the (AZPB70) along with the included software (Figure 11). In the Operational mode, the EEPROM internal to the AZT70/71 has already been programmed with the desired factory settings. Pins DA, CLK, and PV are to be disconnected, thereby allowing the AZT70/71’s internal pull-downs to place the pins at ground potential. In the operational mode, only 3 pins are necessary for hookup (Figure 12). |
