The
OmniTune™ TUA 6039, OmniTune™ TUA 6037’ device combines a mixer-oscillator
block with a digitally programmable phase locked loop (PLL) and a variable gain IF AGC
amplifier for use in TV and VCR tuners, set-top-box and mobile applications. Integrated
narrow band RF AGC functions with output buffer are provided.
The mixer-oscillator block includes three balanced mixers (one mixer with an
unbalanced high-impedance input and two mixers with a balanced low-impedance
input), two 2-pin asymmetrical oscillators for the LOW and the MID band, one 4-pin
symmetrical oscillator for the HIGH band, a reference voltage and a band switch. The
mixer output signal passes a SAW filter driver and an IF AGC amplifier to provide
constant output level ready for A/D sampling.
The PLL block with four pin programmable 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, 125, 142.86 or 166.7 kHz. The tuning process is controlled by a microprocessor
via an I
processor via the I
of the ports (P4) can be also used as input for a 5-level A to D converter (only available
in TUA 6039-2).
