●IC1203 VIDEO-SELECTOR, VHiMM1630EQ-1
This is a video switch with I2C bus control developed for use in high resolution TVs and projection TVs. It can switch
4 color difference signal lines (component signal), 5 S video signal lines and 8 composite signal lines.
●IC1200 SW(MULTIPLEXER), VHiCD4052BP-1
The TC74HC4052A is a high-speed CMOS analog multiplexer/demultiplexer backed by silicon gate CMOS
technology. The multiplexer function includes the selection and mixing of analog and digital signals. The chip
consists of 4 channels (x 2). A digital signal through the control terminal turns on the switch of a corresponding
channel.
●IC1104 IF-Demodurator/PLL, VHiTDA9886+-1
The TDA9886 is an alignment-free multi-standard (PAL, SECAM and NTSC) vision and sound IF signal PLL
demodulator for positive and negative modulation including sound AM and FM processing.
This IC features the following.
* Gain controlled wide-band vision intermediate frequency (VIF) amplifier (AC-coupled).
* Multi-standard true synchronous demodulation with active carrier regeneration (very linear demodulation,
good intermodulation figures reduced harmonics, excellent pulse response).
* Gated phase detector for L/L accent standard.
* Fully integrated VIF Voltage Controlled Oscillator (VCO), alignment-free; frequencies switchable for all
negative modulated standards via I2C bus.
* 4MHz reference frequency input [signal from phase-locked loop (PLL) tuning system] or operating as crystal
oscillator.
* VIF Automatic Gain Control (AGC) detector for gain control operating as a peak sync detector for negative
modulated signals and as a peak white detector for positive modulated signals.
●IC1103 I2C BUS DAC(8bit 2CH), VHiM62332FP-1
The M62332 is an integrated circuit semiconductor of CMOS structure with 2 channels of built-in D/A converters
with output buffer operational amplifiers. The input is 2-wire serial method that is used for the transfer format of digital
data to allow connection with a microprocessor with minimum wiring.
●IC1100 VCA, VHiBA7655AF-1
The BA7655AF is a dual voltage-controlled amplifier IC. By varying the control voltage, the amplifier gain can be
varied in the range of -6dB to +6dB.
●IC2501 MSP, VHiMSP3413G1E
The audio decoding IC is designed to decode S-IF signals and select input audio data. With this chip, the analog
TV-standard worldwide audio signals are processed in the PAL/SECAM regions and the NICAM digital sound
standard is also covered.
●IC3900, IC3901 MAIN AMP, VHiTDA7480/-1
The TDA7480 is an audio class-D amplifier assembled in Power DIP package specially designed for high efficiency
applications.
●IC2506 HP-AMP, VHiBH3544F+-1
This is a dual headphone output amplifier IC. It incorporates a POP noise prevention circuit and a thermal shut down
circuit (150˚C) that are used when turning the power on or off.
●IC1904 HDMI-Receiver, VHiSii9021+-1Q
The Sii9021 is a second generation panel link cinema receiver that is compatible with the HDMI 1.1 (High Definition
Multimedia Interface) specification. The Sii9021 is capable of receiving and outputting two channel digital audio
signals at up to 192 kHz— an excellent solution for digital TVs.
This IC features the following.
1) Digital video interface supports video processors.
2) Analog RGB and YPbPr output: 10-bit DAC.
3) Digital audio interface supports high-end audio systems.
