Description

The TUA60242 device combines a digitally programmable phase locked loop (PLL), with a mixer-oscillator block including two balanced mixers and oscillators for use in TV and VCR tuners.

The PLL block with four selectable chip addresses forms a digitally programmable phase locked loop. With a 4 MHz quartz crystal, the PLL permits precise setting of the frequency of the tuner oscillator up to 1024 MHz in increments of 31.25, 50, 62.5 or 166.7 kHz. The tuning process is controlled by a microprocessor via an I2C bus. The device has three output ports. A flag is set when the loop is locked. It can be read by the processor via the I²C bus.

The mixer-oscillator block includes two balanced mixers (one mixer with highimpedance input and one mixer with a balanced low-impedance input), two frequency and amplitude-stable balanced oscillators for LOW/MID and HIGH, an
IF amplifier, a low-noise reference voltage source, and a band switch.
