TUA 6010XS
preliminary
Wireless Components
Specification, August 1999
2.1
Overview
The
TUA 6010XS
device combines a digitally programmable phase locked loop
(PLL), with a mixer-oscillator block including two balanced mixers and oscilla-
tors for use in TV tuners.
The PLL block with four hard-switched chip addresses forms a digitally pro-
grammable 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 incre-
ments of 62.5 kHz. The tuning process is controlled by a microprocessor via an
I
2
C bus. The device has three output ports, which all can also be used as input
ports (two TTL inputs and one A/D converter input). A flag is set when the loop
is locked. The input ports and lock flag can be read by the processor via the I
2
C
bus. The mixer-oscillator block includes two balanced mixers (double balanced
mixer with 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.
