Functional Description
The TUA6012, TUA6014 devices combine 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 50 kHz, 62.5 kHz or
31.25 kHz. The tuning process is controlled by a microprocessor via an
I
2C Bus. The
device has four output ports, two of them (P0 and P1) can also be used as TTL input
ports. A flag is set when the loop is locked. The input ports and lock flag can be read by
the processor via the
I
2C Bus.
The mixer-oscillator block includes two balanced mixers (double balanced mixer with
high-impedance input for VHF low, VHF high and low-impedance input for UHF), two
frequency and amplitude-stable balanced oscillators for VHF low, VHF high and UHF, a
low-noise reference voltage source and a band switch.
1.3
Application
The ICs are suitable for PAL and NTSC tuners in TV- and VCR-sets or cable set-top
receivers for analog TV and Digital Video Broadcasting.
