Objective data sheet
•
•
•
•
– Reference_byte (4Xh)
– Power_byte_2 (0Eh): sets clock mode
– Power_state_byte_2: puts the tuner in Standby mode
Transition 1 (standard selection):
– IF_Frequency_byte
– IF_AGC_byte
– IF_byte_1
– IR_MIXER_byte_2
– AGC1_byte_1
– AGC2_byte_1
– AGCK_byte_1
– RF_AGC_byte_1
– IR_MIXER_byte_1
– AGC5_byte_1
– PSM_byte_1
– Configures the settings that depends on the chosen received TV standard
Transition 2 (first frequency selection after standard change):
– Power_state_byte_2: wakes the tuner up
– Power_byte_2 (0h): sets clock mode
– RF_Frequency_byte_1
– RF_Frequency_byte_2
– RF_Frequency_byte_3: sets the tuner to the wanted RF frequency
– MSN_byte_1 (41h)
– MSN_byte_2 (01h): RF filters tuning, PLL locking
– Tunes the settings that depend on the RF input frequency, expressed in kHz, RF
– IRQ is generated once operations are completed
Transition 3 (standby):
– Power_byte_2 (0Eh): sets clock mode
– Power_state_byte_2
– Sets the tuner into one of the available Standby modes, keeping the digital data
Transition 4 (frequency selection within same standard):
– RF_Frequency_byte_1
– RF_Frequency_byte_2
– RF_Frequency_byte_3: sets the tuner to the desired RF frequency
– MSN_byte_1 (41h)
– MSN_byte_2 (01h): RF filters tuning, PLL locking
(standard and demodulator dependant)
filters tuning, PLL locking
unchanged
