1. General ICs Information
• IC201: Digital DVBT / VIF Demodulator
Part number: MSB1220LQFP
Sharp code: RH-IXC868WJZZY
The MSB1220L is a multistandard analog TV receiver and DVB-T demodulator.  It is fully compliant with the DVB-T 
specifi cation and Nor Dig unifi ed specifi cation. Converts IF differential signals to MPEG-2 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 fi lter with high rejection capability is also cope with digital or analog adjacent channel. 
The frecuency capture range is suffi cient to compensate for the combined offset introduced by the tuner and broadcaster 
without re-programming the tuner.
It contains a signal processor to offer high quality reception of analog terrestrial multistandard signal.
• IC 306: Audio power IC
Part number: MSH 9000-LF
Sharp code : RH-IXC867WJQZY
10W-Ch audio power class-D operation for driving bridged-tied stereo speakers.
• IC 309: Headphones amplifi er.
Part number: BH3544F
Sharp code: VHIBH3544F+-1Y
The BH3544F is a 6 dB gain headphones amplifi er. It built-in mute function for preventing pop noise when power supply 
turns On or Off.
Moreover , built-in thermal shutdown circuit to prevent short circuit .
•  IC 1007 : 64M-Bit Serial Flash
Part number: MX25L6445EMI-10G-TR
Sharp code: RH-IXD012WJZZY
The MX25L6445EMI ia a 64 M-Bit serial fl ash, 3,3 V single operation.  The fl ash memory stores the main software that 
is used for the main CPU (IC 1001).
• IC 1001: All – in – one DTV Processor 
Part number: MSD3303GX
Sharp code : RH-IXC869WJQZY
The MSD3303GX is a system one chip for fl at panel integrated digital television. It integrating MPEG2 and h.264 high defi nition 
video decoders into a single device. By including a fl exible AV decoder capable of decoding a plethora of high defi nition, USB 
connectivity and a powerful CPU.
•  IC 1002  & IC 1003 : 512 Mb DDR2 SDRAM
Part number: MK4T51163QG
Sharp code: RH-IXC505WJQZQ
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 : 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 confi 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 8101 : Power supply USB port protection 
Part number: TPS2553DBVT-1
Sharp code: RH-IXC975WJZZY
Soft start function witch are required for the power supply  port protection. 1000 mA continuous current load
.
