Stereo Decoder/Noise Blanker TDA 4340X 1 1.
1 Overview Features • Internal reference voltage source • Adjustment free oscillator with ceramic resonator 456 kHz • Pilot dependent mono/stereo switching with hysteresis P-DSO-20-1 • Stereo indicator output • Analogue control of mono/stereo change over (stereo noise control, SNC) • Pilot canceller (19 kHz) • Adjacent channel noise suppression (114 kHz) • MUTE facility • Analogue control of deemphasis (high cut control, HCC).
• Stereo inputs for additional signal source at output amplifiers • Interference noise detector with integrated high-pass filter • (IF level signal or MPX input) • MPX input low-pass filter • Noise blanking at MPX demodula...
