PC I/F unit
∫
IC10004 (CXA3506R)
3-ch, 8-bit 120MSPS A/D converter incorporating AMP and PLL.
This IC process video signals supplied to the interface board. On the main side, video signals (analog RGB)
from CN6 are inputted to IN1 of IC10004. On the PC side, vide signals (analog RGB) from CN8 are inputted to
IN2 of IC10004.
Converted digital signals are sent to IC10025.
∫
IC10310 (TLC5733A)
3-ch, 8-bit 20MSPS A/D converter.
This IC processes video signals supplied to the interface board. It receives analog signals (YCbCr) from CN6
and sends converted digital signals to IC10310.
The incoming video signal is converted to digital one and fed 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 channels: V0 and V1. V1 is for sub 480i 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.
∫
It creates OSD signals.
The incoming video signal is fed to IC10413.
∫
IC10413 (SII170)
Panel link transmitter.
This IC converts 8-bit RGB image data received from IC10025 into TMDS differential signals and sends the
resulting digital signals to the monitor.
HDCP function is provided.
∫
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.
