Functional Description
The TUA6026, TUA6028 device combines a digitally programmable phase locked loop (PLL), with a mixer-
oscillator block including two balanced mixers and oscillators for use in TV tuners.
The PLL block with four hard-switched 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
900 MHz in increments of 62.5 kHz. The tuning process is controlled by a microprocessor via an I2C bus. The
device has four output ports, two of them (P0 and P1) can also be used as TTL input ports. A ag is set when
the loop is locked. The input ports and lock ag can be read by the processor via the I2C bus.
The mixer-oscillator block includes two balanced mixers (one mixer with high-impedance input and one mixer
with a balanced low-impedance input), two frequency and amplitude-stable balanced oscillators for VHF,
HYPER and UHF, a low-noise reference voltage source and a band switch.

Application
The IC is suitable for NTSC and PAL tuners in TV- and VCR-sets or cable set-top receivers for analog TV and
Digital Video Broadcasting.
