Preliminary specification
Advanced modem/audio analog front-end
UCB1300
The second ADC start mode gives the opportunity to start the ADC at the rising edge of the signal connected to the
ADCSYNC pin. The 0->1 transition of the ADC_START bit will arm the ADC, such that it will start in the first detected
rising edgeof theADCSYNC signal.Alsoin thismode, theinternal start/stoplogic willdetect whethertheADCmultiplexer
settings are changed simultaneously with the ADC start bit and it will add a delay to ensure sufficient setting time for the
internal track and hold circuit. A rising edge of the signal connected to the ADCSYNC pin occurring during this tracking
time is ignored; the ADC conversion is started on the first rising edge detected after this delay time. This leads to the
following two timing diagrams of the ADC conversion.
