Description
The STV4100 terrestrial tuner is a direct-
conversion (zero-IF) receiver with quadrature
outputs intended for digital TV broadcasting.
On each VHF and UHF input is a low noise
amplifier with both switchable and variable gain 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 is programmable via
a dedicated pin.
The LO signals are provided by an integrated PLL
which contains an on-chip voltage controlled
oscillator meeting stringent phase noise
requirements. The LO frequencies are
programmable.
The comparison frequency for the
phase/frequency detector is generated by dividing
the crystal oscillator reference frequency. The
crystal frequency can be from 16 MHz to 31 MHz
depending on application.
