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
speci
fi
cation and Nor Dig uni
fi
ed speci
fi
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 suf
fi
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 ampli
fi
er.
Part number: BH3544F
Sharp code: VHI-1Y
The BH3544F is a 6 dB gain headphones ampli
fi
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 :
128M-Bit Serial Flash
Part number: MX25L12805DMI
Sharp code: RH-IXC870WJZZY
The MX25L12805DMI ia a 128 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 de
fi
nition
video decoders into a single device. By including a
fl
exible AV decoder capable of decoding a plethora of high de
fi
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: M24C02W81EY
Sharp code: VHIM24C02W61EY
The M24C02W81EY is a 2-wire (I2C bus type) serial EEPROM that is electrically programmable. This NVM memory is
associated to the MAIN MICRO. This EEPROM chip stores the data structure used to carry con
fi
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 M24512-WMN6T ST
Sharp code: RH-IXC986WJZZY
