IC8455
VHIBR24S64F-1Y
64K bit E2PROM
The BR24S64W is a 64Kbit-2-wire (I2C bus type) serial EEPROM that can
be programmed electrically.
This IC stores the menu data and the adjustment value data of adjustment
process mode etc.
The data is given out by commands from the main microprocessor.
IC506
VHiM3221EiP-1Y
RS232C-DRIVER
The MAX3221E is a single driver, single receiver RS-232 solution operating
from a single Vcc supply. The RS-232 pins provide IEC G1000-4-2 ESD
Protection. The device meets the requirements of TIA/EIA-232-F and pro-
vides the electrical interface between an asynchronous communication
controller and the serial-port connector. The charge pump and four small
external capacitors allow operation from a single 3V to 5.5V supply.
IC4402
VHiMT5135AE-1Q
CI controller
DTB-T/C Demodulator
This is a control IC for PCMCIA cards. This controls information on IC cards
inserted into the PCMCIA card slot (SC4401) or information on software
version upgrade cards saved on flash memories to transfer the data to
CPUs and memories.
IC2005

The SiI9387 HDMI port processor is the second generation of HDMI
devices that support revision 1.4 of the HDMI specification.
The main feature is as follows.
1) 5-input, 1-output HDMI port processor.
2) Audio Return Channel that allows an S/PDIF uplink from HDMI sink
device to an HDMI source available in one reciver port.
3) Integrated TMDS receiver and transmitter cores capable of receiving
and transmitting at 2.25Gbps.
4) Supports video resolutions up to 1080p, 60Hz, 12bit or 720p/1080i,
120Hz,12bit.
5) Receiver fully comply with DVI1.0, HDCP and several optional 3D for-
mats described in the HDMI1.4 specifications.
IC9505

Ethernet Bus Interface
The IC is a USB 2.0 hub device that complies with the Universal Serial Bus
(USB) Specification Revision 2.0 and works up to 480 Mbps. USB 2.0 com-
pliant transceivers are integrated for upstream and all downstream ports.
The IC4 works backward compatible either when any one of the down-
stream ports is connected to a USB 1.1 compliant device, or when the
upstream port is connected to a USB 1.1 compliant host.
IC2703
VHiYDA164BZ-1Y
Audio-AMP
This IC is digital audio power amplifier with digital audio interface.
The power-supply voltage is corresponded to A.5V~18V and the maximum
output is 20Wx2ch.

(LC-60LE635E,RU/
638E only)
RH-iXC563WJQZY
LNB supply and
control
It is IC for amplifying the feeble electric wave sent from satellite broadcast-
ing on the level which can treat a decoder, and changing and processing
signal.
