DUNTKF639WE (Main Unit)
• IC 201: Digital DVBT / VIF Demodulator
Part number: MSB1222-LF
Sharp code: RH-IXD148WJZZQ
The MSB1222-LF is a DVB-T/DVB-C demodulator. It is fully compliant with the DVB-T (ETSI ET 300 744), D-Book 5.0
and Nordig unifi ed specifi cation. Also is compliant with DVB-C (EN 300429) and ITU-T J.83 Annex A/C. Converts IF dif-
ferential 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 fi lter with high rejection
capability is als o cope with digital or analog adjacent channel. The frequency capture range is suffi cient to compensate
for the combined offset introduced by the tuner and broadcaster without re-programming the tuner.
• 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: BH3547-E2
Sharp code: VHIBH3547F+-1L
The BH3547 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-IXC869WJQZQ
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: 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 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 8102 : Power supply USB port protection
Part number: AAT4614IGU-2-T1
Sharp code: RH-IXD187WJZZY
