· IC1905 : HDMI RECEIVER
Part number:
Sii9021
Sharp code:
VHISII9021+-1Q
The Sii9021 is a second generation panel link cinema receiver that is compatible with the HDMI 1.1 (High Definition
Multimedia Interface) specification. The Sii9021 is capable of receiving and outputting two channel digital audio sig-
nals at up to 192 kHz— an excellent solution for digital TVs.
This IC features the following.
1) Digital video interface supports video processors.
2) Analog RGB and YPbPr output: 10-bit DAC.
3) Digital audio interface supports high-end audio systems.
· IC2301 : RS-232 TRANSMITTERS/RECEIVERS
Part number:
ISL83220
Sharp code:
VHIISL83220-1Y
The ISL83220E is a 3.0V to 5.5V powered RS-232 transmitter/receiver,+/-15kV ESD protected, minimum data rate
250 kpbs.
· IC2303 : NVM OF PC MODE (EDID)
Part number:
BR24C21F
Sharp code:
VHIBR24C21F-1Y
This IC is a 2-wire (I2C bus type) serial EEPROM this is electrically programmable. This EEPROM chip stores the
data structure used to carry configuration information for optimal use of a display (EDID data).
· IC2701 : SYNC SELECT
Part number:
TVHC153T
Sharp code:
VHITVHC153T-1Y
This VHC153 is a high-speed Dual 4-input multiplexer with common select inputs and individual enable inputs for
each section.
·
IC2702 & IC2705: VIDEO INPUT SELECTOR.
Part number: MM1507XN
Sharp code: VHIMM1507XN-1Y
This IC extends the series of ICs for video/audio signal switching, with a 2-input 1-output single video switch with 75Ω
driver and input clamp.
IC2704 : HDMI & RGB SOUND MULTIPLEXER
Part number:
CD4052BP
Sharp code:
VHICD4052BP-1Y
The TC74HC4052A is a high-speed CMOS analog multiplexer/demultiplexer backed by silicon gate CMOS technol-
ogy. The multiplexer function includes the selection and mixing of analog and digital signals. The chip consists of 4
channels (x 2). A digital signal through the control terminal turns on the switch of a corresponding channel.
· IC3001 : NVM 64Kb-E2PROM
Part number:
BR24L64F
Sharp code:
VHIBR24L64F-1Y
The BR24L64F is a 2-wire (I2C bus type) serial EEPROM that is electrically programmable. This IC stores the control
data of system contents (last memory, for example) for the main microprocessor’s AV PWB and main PWB. The data
is given out by commands from the main microprocessor.
· IC3002 : VIDEO PROCESSOR
Part number:
VCT6973G-B2
Sharp code:
RH-IXB624WJZZQ
The VCT 6wxyP family is dedicated to high-quality FPD and double-scan TV sets. The memory and program
ROM are integrated in the IC. Modular design and deep submicron technology allow the integration of audio,
video, teletext, OSD, and controller-related functionalities. They cover the whole range of flat-panel display TVs.
The IC is based on proven functional blocks of existing products like VCT 49xxI, VSP 94x5B, and DPS 94xxB.
Each member of the IC family contains the entire audio, video, upconversion processing for 4:3 and 16:9 50/60 Hz
progressive or 100/120 Hz interlaced stereo TV sets plus the control/data interface for flat-panel displays. The inte-
grated microcontroller is supported by a powerful OSD and graphics generator with integrated teletext acquisition.
The VCT 6wxyP family provides a front-end video processing unit with 4 CVBS-Y/C or component inputs for
HDTV, EDTV, and SDTV. A VBI slicer, support of 1000 pages of teletext, and a 3-D comb filter for PAL and NTSC
