STV6110A 8PSK/QPSK low-power 3.3 V satellite tuner IC

The STV6110A satellite tuner is a directconversion (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 I²C bus.

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 phasefrequency 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.
