Sharp code: RH-IXC868WJZZQ
The MSB1220-LF is a DVB-T demodulator. It is fully compliant with the DVB-T (ETSI ET 300 744), D-Book 5.0 and Nor-
dig uni ed speci cation. Converts IF differential signals to MPEG-2/4 transport stream format. It can be used in all 2k,
4k and 8 k modes. The device includes a high performance 11 bit A/D converter capable of accepting direct IF at 36 or
44 Mhz. A digital lter with high rejection capability is also cope with digital or analog adjacent channel. The frequency
capture range is suf cient to compensate for the combined offset introduced by the tuner and broadcaster without re-
programming the tuner.

• IC 8102 : Power supply USB port protection
Part number: AAT4614IGU-2-T1
Sharp code: RH-IXD187WJZZY
Sharp code: RH-IXD187WJZZY
The AAT4614 SmartSwitch is a current limited P-channel MOSFET power switch designed for high side load switching
applications. This switch operates with inputs ranging from 2.4V to 5.5V, making it ideal for both 3V and 5V systems. An
integrated current-limiting circuit protects the input supply against large currents which may cause the supply to fall out of
regulation. Reverse current blocking is provided to protect the load switch from reverse current potentials while the device is
shutdown. The AAT4614 is also protected from thermal overload which is limited by power dissipation and junction tempera-
tures. Current limit threshold is programmed with a resistor from SET to ground and has been adjusted for levels up to 1.1A.
