TDA4340X Datasheet (Siemens Semiconductor) - Stereo Decoder/Noise Blanker

TDA4340X, Stereo Decoder/Noise Blanker

Power Supply, Reference Current A temperature stable, low noise reference voltage generator is used for better ripple rejection and for the generation of a reference current.

This current is used as a time base for the deemphasis, the gate time of the pulse former, and the pilot cancellation, avoid
