INB (pos) and INA (pos) are connected to a reference voltage 2.5 V by dividing VDD
supply. INA (neg) and INB (neg) is connected to HEADPHONER, HEADPHONEL outputs
of VCTH. Those audio outputs are parallel to LINE_OUT connectors. Headphone has
also detection property from the connector. It is controlled by VCTH GPIO pin “HP
Detect”.
Demodulators
MSB1210
The MSB1210 is the world’s 1
st
hybrid demodulator to receive both analog
terrestrial TV and digital TV signals. It contains the state of the art Signal Processing to
offer high quality receptionof analog terrestrial TV signals compliant with PAL B(G, PAL I
standards. It also contains a superior COFDM demodulator. It can be used in all 2K, 4K
and 8K modes with 5,6,7 and 8 MHz channels and is capable of receiving all modes of
transmission.
The device includes a high performance 11 bit A/D converter capable of accepting
direct IF at 36 or 44 MHz. It can also support low IF and ZIF signaling. Sampling rates
required for all these frequencies in OFDM channels can be generated from a single
24MHz crystal.
