8PSK/QPSK low-power 3.3 V satellite tuner IC
Description
The STV6110A satellite tuner is a direct-
conversion (zero IF) receiver dedicated to digital
TV broadcasting.
On the RF input is a low noise amplifier (LNA),
with buffer to supply the RF output for
loop-through, and a continuously variable gain
LNA to ensure an optimal signal level for the two
mixers. Each mixer, which down-converts the
signal to baseband, is followed by a low-pass filter
and amplifier. The baseband gain can be varied
by programming a register via the I
The LO signals are provided by an integrated PLL
which contains an on-chip voltage controlled
oscillator (VCO) meeting stringent phase noise
requirements. The PLL loop filter is integrated.
The LO frequencies are programmable.
The comparison frequency for the phase-
frequency detector (PFD) is generated by dividing
the crystal oscillator reference frequency. The
crystal frequency can be from 16 MHz to 32 MHz
depending on application.
