1. MAJOR IC INFORMATIONS
1.1. IC2502 (VHi-1Q)
This IC is a versatile High Definition Multimedia Interface 2.0 (HDMI
®
) transmitter/port processor, with support for Mobile
High-Definition Link 3 (MHL ® ) and High-bandwidth Digital Content Protection 2.2 (HDCP). The device’s 18 Gb/s transmitter and receiver features
support delivery of full resolution 4K Ultra High Definition (UltraHD) 4:4:4 video to a 4K television set at 50 Hz or 60 Hz frame rate.
As port processor, all four inputs support HDMI 2.0 at up to 18 Gb/s, and two of the inputs can also support MHL 3 input at resolutions of up to 4K
@30 Hz. The three outputs offer a flexible configuration, including the ability to split an 18 Gb/s signal into two 9 Gb/s outputs. Audio and video can be
routed to separate transmitters and two separate 300 MHz output streams can be routed from two input sources.
1.2. IC2501 (VHiW25X40CL-1Y) SPI-Flash for IC2501
This is 4M-bit SPI Flash device stores the F/W of IC2501.
1.3. IC601 (VHiM3221EiP-1Y)
This IC is a high speed, single-channel RS-232 transceiver interface device that operates from a single 3.3V power supply.
The device provides the electrical interface between an asynchronous communication controller and the serial-port connector.
This device operates at data signaling rates up to 460kbit/s.
All RS-232 (Tout and Rin) and CMOS (Tin and Rout) inputs and outputs are protected against electrostatic discharge (up to +/- 15kV ESD protection).
1.4. IC3303 (RH-iXD775WJQZQ)
This IC consists of a DTV front-end demodulator, a backend decoder and a TV controller and offers high integration for advanced applications. It inte-
grates a transport de-multiplexer, a high definition video decoder, an audio decoder, a V-by-One transmitter, and an NTSC/PAL/SECAM TV decoder
with a 3D comb filter (NTSC/PAL).
This IC supports Full-HD MPEG1/2/4/h.264/DiviX/VC1/RM/AVS/VP6/VP8 and UHD h.264/HEVC video decoder standards, and JPEG. A 3D comb fil-
ter added to the TV decoder recovers great details for still pictures. The special color processing technology provides a natural, deep colors and true
studio quality video. Moreover, this IC has built-in high resolution and high quality audio codec.
It integrates high-quality HDMI1.4a, high speed VGA ADC, V-by-One, USB2.0/3.0 receiver, Ethernet MAC+PHY, dual core CPU and 1M bytes L2
cache, TCON, panel overdrive, OpenGL ES 1.1/2.0/3.0, OpenVG 1.1, DirectX DX11 compliant 3D graphic engine, and ATSC/DVB-T/DVB-C demod-
ulators.
This IC provides consumers with a true UHD 60Hz and Full-HD 120Hz experience. It integrates high-quality Full-HD ME/MC technology.
1.5. IC3501, IC3502, IC3503, IC3504, IC3505 (RH-iXD751WJQZQ)
These are 4G-bit (256M x 16bit) DDR3-1866 synchronous DRAM.
1.6. IC3151 (VHiM24C64TP-1Y)
This is 64k-bit EEPROM device including the user setting and the uP setting.
1.7. IC3101 (RH-iXD793WJQZQ)
The 16G-byte eMMC flash memory device stores the main CPU program.
1.8. IC501 (VH+-1Y)
This IC is audio amplifier for line-out/head-phone.
1.9. IC1701, IC1801 (VHiYDA176DL-1Y)
The Class-D type digital audio power amplifier YDA176 gives high performance 10W x2ch and maximum continuous output of woofer output 15W. It
adjusts TVs audio quality.
1.10. IC1601 (VHiCY65632L-1Q)
This IC is USB 2.0 Hub. Up to four downstream ports support.
