CE6353 COFDM DECODER : Introduction (IC 7507 TERMINAL UNIT)
The Intel® CE 6353 DVB-T demodulator meets the performance requirements of NorDig Unified 1.0.2 standard.
The device includes a high-performance 10-bit A/D converter capable of accepting direct IF integrated digital filtering
and requires only a single 8 MHz channel SAW filter for 6, 7 and 8 MHz COFDM signal reception, plus a 7-bit ADC for
RF level indication.
An advanced hard-wired on-chip state machine controls all acquisition and tracking operations, minimizing software
overhead and resulting in fast auto scan and auto signal re-acquisition.
The Intel CE 6353 DVB-T demodulator accepts the classic TV IF frequencies of 36/44 MHz and low IF down to
4.57 MHz.
It provides tuner IF AGC control, and RF AGC read using a 7-bit ADC for calculated RF signal strength indication.

MM3151XQ VIDEO SWITCH SELECTOR: Introduction (IC 506 TERMINAL UNIT)
I2C Bus-Controlled Video Switching. This product employs Pure-CMOS process for the first time as a video switch,
to add power-saving function, and thus realizes lowered power consumption. This product also includes a filter which
eliminates sampling noise at DAC when wide band component signal (D3, D4) are passing, and therefore enables the
specification for select filtering (for D1~D4).
AK4683EQ CODEC AUDIO: Introduction (IC 1404 TERMINAL UNIT)
This versatile chip integrates a 2-channel ADC, 4-four channel DAC (192 kHz sampling), a headphone amplifier and a
192 kHz compatible Digital Audio Receiver and Transmitter (DIR/DIT) with four inputs and one output. The AK4683's
digital audio interface (S/PDIF) and headphone amplifier make it easy to put together high performance home theatre
C
systems.
The pre-ADC stage has a preamp with 6-channel input selector.The AK4683 is a single chip CODEC that includes two
channels of ADC and four channels of DAC. The ADC outputs 24bit data and the DAC accepts up to 24bit input data.
The also has digital audio receiver (DIR) and transmitter (DIT) compatible with 192kHz, 24bits.
The DIR can automatically detect a Non-PCM bit stream such as Dolby Digital (AC-3)*. The AK4683 has a dynamic
range of 100dB for ADC, 106dB for DAC and is well suited for digital TV and home theater system.
TAS3108D AUDIO DSP: Introduction (IC 1403 TERMINAL UNIT)
The TAS3108 is a fully programmable high-performance audio processor.
It uses an efficient, custom, multi-instruction programming
environment optimized for digital audio processing algorithms.
D
The TAS3108 architecture provides high-quality audio processing by using a 48-bit data path.
R2S15500SP SOUND MULTIPLEXOR: Introduction (IC 1402 TERMINAL UNIT)
The device is a sound multiplex decoder IC developed for TV/VCR sets.
It supports NICAM and A2 system so it covers all standards of audio transmissions of European and Asian terrestrial TV
broadcasts.
It incorporates high-speed ADC, and all the processing has been achieved by digital processing including the
demodulator.
YDA147-SZE2 DIGITAL AUDIO POWER AMPLIFIER: Introduction (IC 1301 TERMINAL UNIT)
E
20W x ch / 4Ω digital audio power amplifier. The IC is class D amplifier equipped with the function for the dynamic
self-adjustment of the output volume in proportion to the amplitude of the input signal. The company calls the function of
automatic adjustment of the installed output volume "DRC (dynamic range compression)".
The modulation method adopted PWM. An external LC filter is unnecessary.
It only has to supply the output signal directly to the speaker. It has the output control function to prevent an excessive
input to the speaker. The maximum output electric power can be set to an arbitrary size by external resistance.
Besides this, the protection function to overheating and the overcurrent was installed.
The switching operation of power MOS-FET is installed and the technology that carefully controls the slewing rate is
installed.
Moreover, the automatic offset calibration circuit that suppresses the pop noise when the power supply starts is built into.
