GENERAL DESCRIPTION
Multistandard satellite sound IF device consisting of a mixer and a voltage controlled oscillator (VCO) as a frequency converter that can be continuously tuned in 10 kHz increments with crystal accuracy by means of a PLL, two FM limiter amplifiers with PLL FM demodulators followed by two Wegener PANDA1TM expanders. The AF signal passes through two switches. In front of one FM section an IF multiplexer is used to select the IF bandwidth. The switching functions and settings of the PLL are controlled by an I2C-bus.
