•  IC 201 (LE210): Digital DVBT / VIF Demodulator

Part number: MSB1220LQFP
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.

Sharp code : RH-IXC869WJQZQ

The MSD3303GX is a system one chip for  at panel integrated digital television. It integrating MPEG2 and h.264 high de nition 
video decoders into a single device. By including a  exible AV decoder capable of decoding a plethora of high de nition, USB 
connectivity and a powerful CPU.

•  IC 1002  & IC 1003 : 512 Mb DDR2 SDRAM

Part number:  K4T51163QI
Sharp code: RH-IXD228WJZZQ

The 512Mb DDR2 SDRAM is organized as 16Mbit x 8 I/Os x 4 banks device. This synchronous device achieves high 
speed double-data-rate transfer rates of up to 800Mb/sec/pin (DDR2-800) for general applications.
All of the control and address inputs are synchronized with a pair of externally supplied differential clocks (CK rising and 
CK falling).
This device operates with single 1,8V power supply .

•  IC 1901, IC 1902 & IC 1903 : NVM of HDMI inputs (EDID)

Part number: K24C02C
Sharp code: RH-IXD080WJZZY

The K24C02C is a 2-wire (I2C bus type) serial EEPROM that is electrically programmable. This NVM memory is as-
sociated to the MAIN MICRO. This EEPROM chip stores the data structure used to carry con guration information for 
optimal use of a display (EDID data) when use a HDMI signal input.

•  IC 1006 : NVM of settings and HDCP data 

Part number: IC M24C64 
Sharp code: VHIM24C64WN-1Y

•  IC 8102 : Power supply USB port protection 

Part number: AAT4614IGU-2-T1
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.
