3-V terrestrial tuner IC Data Brief Features ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! Description The STV4100 terrestrial tuner is a directconversion (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 re...
