(in certain versions) are also available. The front-end unit further allows to process an SD and an HD source in paral-
lel, thus enabling PiP and PaP functionality. Motion-adaptive de-interlacing, temporal noise reduction, and film mode
detection are based on a unified memory technology.
Post-scaling in the display processing block ensures the desired output format. Display processing is supported by
an 8-bit 8051-compatible controller. By means of powerful alpha-blending, the graphics mixer composes the output
image from following image layers: the video layer, the OSD layer and the pixel graphics layer.
The audio part consists of a multistandard sound IF demodulator and a baseband processor supporting all desired
sound features in this range.
A connection for additional features, such as advanced motion compensation via -Micronas’ FRC 94xyA, is also
provided.

IC3005: RESET IC FOR VCTP (IC3002)
Part number: BU4215G
Sharp code: VHIBU4215G+-1Y
Low voltage detector IC with adjustable output delay. Standard detection voltage = 1.5V
FD604WJ (AV UNIT):
· IC301 & IC302 : AUDIO AMPLIFIER
Part number:
TDA8931T
Sharp code:
VHITDA893T-1Y
The TDA8931 is a switching power stage for high efficiency class-D audio power amplifier systems. The IC has a high
efficiency so that a heat sink is not required up to 20W (RMS).
· IC303 : HEADPHONE AMPLIFIER
Part number:
NJM4558M
Sharp code:
VHINJM4558M-1Y
The NJM4558 is a dual high-gain operational amplifier internally compensated and constructed on a single silicon
chip using an advanced epitaxial process.
· IC1101 & IC1102: VIDEO OUTPUT
Part number:
MM1506XN
Sharp code:
VHIMM1506XN-1Y
This IC extends the series of ICs for video/audio signal switching, with a 2-input 1-output single video switch with 75W
driver and input bias (6dB gain).
· IC1201: VIDEO INPUT
Part number:
MM1507XN
Sharp code:
VHIMM1506XN-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.
FD605WJ (POWER SUPPLY UNIT):
· IC704: POWER SUPPLY CONTROLLER FOR INVERTER
Part number:
MR4020 (26”) / MR4030 (32”/37”)
Sharp code:
VHIMR4020++-1 / VHIMR4030++-1
A high speed 900V IGBT makes ideal partial resonance operation which ensures high efficiency and low noise.
Very low power consumption at micro-loads (burst mode). Start-up circuit eliminates the need for start-up resistor.
Excess current protection (ON period limitation, primary current limitation), excess voltage protection, and thermal
shut-down function are incorporated.
