QN8006B/8006LB
4.6 Channel Setting
The QN8006 supports both auto tuning/scan and manual channel settings.
Manual Channel Setting
By programming channel index CH[9:0], the RF channel can be set to any frequency between 76 MHz ~ 108 MHz in 50
kHz steps. The channel index and RF frequency have the following relationship:
FRF = (76 + 0.05 x Channel Index), where FRF is the RF frequency in MHz.
The QN8006 has an integrated crystal oscillator and supports various crystal frequencies. Alternatively, the QN8006 can
be driven externally by various clock frequencies.
Clear Channel Scan
The QN8006 can automatically find the clearest channel and return the channel information for FM transmission. The
start, stop and frequency step of searching as well as upward or downward searching can be programmed through the
serial interface.
Auto Tuning
In receive mode, the QN8006 can automatically tune to stations having good signal quality. The start, stop and frequency
step of tuning as well as upward or downward tuning can be programmed through the serial interface.
