Product Description
The TUA 6039F-2, TUA 6037F ’OmniTuneTUA 6039F-2, OmniTuneTUA 6037F’
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
2C bus. A flag is set when the loop is locked. The lock flag can be read by the
processor via the I
2C bus. The device has 5 output ports and a X_TAL output buffer. One
of the ports (P4) can be also used as input for a 5-level A to D converter (only available
in TUA 6039F-2).
