From a functional standpoint, each of the two high-sensitivity receivers in the TSH511 includes an RF front-end low-noise amplifier, an intermediate amplifier that connects to two external filters, voltage limiter, quadrature FM demodulator, and audio buffer with squelch circuit.
Power management is automatically controlled through sink device detection, and output squelch circuits are controlled by input signal detection.
