Furthermore, the TUA 6045-2 integrates a buffered RF AGC and programmable clock signals for an external DC-DC up converter. The integrated mixer oscillator function comprises of three balanced mixers. The first mixer has an unbalanced high impedance input while the other two have balance low impedance inputs. The tuner also has firstly, 2-pin asymmetric oscillators for both Low and Mid bands and secondly a 4-pin symmetrical oscillator for High band operations including a band selector switch. The output signal from the mixer is amplified via a SAW filter driver followed by variable gain amplifier stage in order to achieve a constant output level used for A/D conversion. All functions can be programmed with up to four different IC addresses. Also, the PLL connected to a 4-16 MHz reference crystal which is buffered on-chip, allows the setting of the tuner oscillator with a minimum step size of 20 kHz. A Lock flag will be set once the PLL is locked and communicated via the I2C/3-Wire bus. The complete control setting of the IC is done by a microprocessor via the I2C/3-Wire bus. The device also has three output ports of which P2 can be configured as a programmable output voltage port.
