This IC is optically connected to an external digital audio device, allowing you to enjoy digital sound on an
This IC not only processes the audio signal of all standard analog TV broadcasts worldwide, it also
incorporates the NICAM digital sound standard.
This switch is used to select the digital tuner output, analog tuner output, composite video input, and S-
This IC is used to store TELTEXT signals (which are broadcast simultaneously) in the memory.
These signals are output by a command from the TELTEXT micon as necessary.
It incorporates a TELTEXT micon program, and it outputs data on a command from the TELTEXT micon.
Programming System (VPS), Program Delivery Control (PDC), and Wide Screen Signaling (WSS) data
used for PAL plus transmissions (line23).
this microcomputer uses high-functionality commands, it has a high-command efficiency. It has a 1Mbyte
address space and it has the ability to carry out instructions at high speed. It also incorporates an OSD and
a data slicer. This microcomputer supports closed captions (an official teletext broadcast standard for hearing-
impaired people) and ID1 (525p compliant).
This IC works as a 4H comb filter, Y/C separator, PAL/NTSC/SECAM color decoder, PIP processor, etc. Its
results are output as an 8-bit Y-OUT/CrCb-OUT signal which is supplied to a scaler.
The FLI2310 is a highly integrated digital video format converter for DTV and DVD applications using
patented deinterlacing and post-processing algorithms from Faroudja Laboratories, coupled with highly
flexible scaling, a wide variety of aspect ratio conversions, and other special video enhancing features to
produce the highest quality image.
This IC is used by the progressive converter, format converter (image conversion), and noise reducer on
the scaler (IC4601) and LCD control IC (IC4512). It is also used to store a video signal when correcting the
QS image quality.
It outputs a control signal for driving the liquid crystal panel.
Additionally, it has the function of a Quick Shoot-compliant OSD MIX (including control of the temperature
output buffer amplifier (18 circuits), a COM buffer amplifier, and a REF amplifier (reference power supply).
It downloads the program stored in the E2PROM IC3407 to the built-in PRAM and then executes it.
Audio data input and output are performed through an I2S serial host interface. There are three data inputs
and three data outputs.
Audio data input and output are performed through an I2S serial host interface.
It incorporates a POP noise prevention circuit and a thermal shut down circuit (150ÅãC) that are used when
turning the power on or off.
a horizontal oscillation circuit, and a phase-comparison circuit. When a video signal is input, a composite
synchronization signal (SYNC), a vertical synchronization signal (VD), and a horizontal synchronization
signal (HD) are produced.
This IC has both synchronous separation and AFC (Auto Frequency Control) functions.
