· IC1710: CPLD
Part number: EPM240T
Sharp code: RH-IXB823WJZZQ
This IC is a CPLD of Altera MAXII family and use 240 logic elements (LEs) (192 equivalent macrocells)
MAX II devices offer high I/O counts, fast performance. MAX II devices are designed to reduce cost and power while
providing programmable solutions for applications such as bus bridging, I/O expansion, power-on reset (POR)
and sequencing control, and device confi guration control.
This device controls ON/OFF power supply, signals for inverter unit and etc.
FD604WJ (AV UNIT):
· IC301 & IC302 : AUDIO AMPLIFIER
Part number:
TDA8931T
Sharp code:
VHITDA893T-1Y
The TDA8931 is a switching power stage for high effi ciency class-D audio power amplifi er systems. The IC has a high
effi ciency 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 amplifi er internally compensated and constructed on a single silicon
chip using an advanced epitaxial process.
IC1101 & IC1102: SCART VIDEO OUTPUT DRIVER.
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 75Ω
driver and input bias (6dB gain).
IC1201: 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.
