Description

Multistandard satellite sound IF TDA6170X 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 TDA6170X signal passes through two switches. Each switch can select the AF sources and the mono / stereo mode the de-emphasis networks together with the two following volume control stages with audio buffers. In front of one FM section an IF multiplexer is used to select the IF bandwidth. The switching functions and settings of the PLL TDA6170X are controlled by an I2C-bus.
