» PC I/F unit
∫ IC10004 (CX3506R)
3-channel, 8-bit, 120 MSPS A/D converter incorporating AMP and PLL.
This IC is for video signals inputted to the PC I/F unit and used for one-screen and two-screen applications,
and for PC signals inputted to the front panel.
It provides A/D conversion of video signals (analog RGB) inputted to IN1 from CN10006 and PC signals
(analog RGB) inputted to IN2 from CN10008.
Converted digital signals are sent to IC10025.
∫ IC10310 (TLC5733A)
3-channel, 8-bit, 20 MSPS A/D converter.
This IC is for video signals inputted to the PC I/F unit and used for two-screen application.
It provides A/D conversion of video signals (analog YcbCr) inputted to IC10310 from CN10006.
Converted digital signals are sent to IC10025.
∫ IC10025 (IXA091WJ)
IC for I/P conversion and scaling of digital image according to the output resolution, and for data conversion.
There are two input channel: V0 and V1. V1 is for sub 480i/580i input processing for two-screen application. V0
is for processing all signals for main used for one and two-screen applications.
The IC generates clamp signals based on input synchronization signals.
It also performs data matrix conversion, and creates OSD signals.
Processed signals are sent to IC10413.
∫ IC10413 (SII170)
Panel link transmitter.
This IC converts 8-bit RGB image data received from IC10025 into TMDS differential signals and sends to the
display.
(Note:When replace this IC, PWB replacement correspondece.)
∫ IC10001 (IX3270CE)
One-chip RISC microprocessor.
This IC communicates with the monitor and controls the system operation.
It controls all the ICs located in the AVC system.
∫ IC10405 (µPD4721G)
RS-232 line driver/receiver conforming to EIA/TIA-232-E.
This IC enables the system to be controlled from a PC connected to the system.
It also allows IC10001 to be upgraded using the PC.
