Introduction
In the STV6111 satellite tuner, on the RF input, there is a variable gain, low-noise amplifier
(VGLNA). The RF gain is monitored by an automatic gain control (AGC) circuit to ensure an
optimal signal level for the two mixers. Each mixer, which down-converts the signal to the
baseband, is followed by an AGC-controlled VGA, a low-pass filter and a second VGA.
The local oscillator signals are provided by an integrated fractional-N phase locked loop
(PLL), which contains an on-chip voltage-controlled oscillator meeting stringent phase noise
requirements. The PLL loop filter is partly integrated. The local oscillator frequencies are
programmable between 950 MHz and 2150 MHz.
The comparison frequency for the phase-frequency detector is generated by dividing the
crystal oscillator reference frequency. The crystal frequency may be within the range
15 MHz to 31 MHz depending on the application.
Features
Variable gain low noise amplifier input structure
Single flexible Xtal
Fractional-N PLL
High symbol rate support
Doc ID 022528 Rev 1
Benefits
Allows flexible compromise between linearity and
noise figure allowing the most difficult signals to be
extracted in the most congested and noisy
conditions
Wide choice of crystal frequencies with robust
clock buffer to drive second tuners and
demodulators allowing eBoM savings
Low phase noise for low packet error rate under
extreme conditions (e.g. low symbol rates), fast
locking
Allows more efficient exploitation of Ku (up to
60 Msps) and Ka band (up to ~220 Msps) satellites
