Page 42: Major Ic Informations
LC-26GA5H/M/X MAJOR IC INFORMATIONS ∫ IC3801 (CXA2069Q) This is a 7-input, 3-output selector. All the video signals but the PC and component lines, coming from the input terminals and tuner, as well as all the audio signals are fed into this IC for being selected.
Page 43 LC-26GA5H/M/X ∫ IC502 (CXD2096Q) The CXD2096Q is also a digital chroma decoder. The main signal is processed for the luminance signal, chroma signal and sync signal with respect to the adaptive 2D comb filter PAL/NTSC/SECAM system. The output is 10-bit Y/CbCr (ITU_R601).
Page 44 LC-26GA5H/M/X ∫ IC4602 (IXB227WJ) The EEPROM is designed to store the 10-bit gamma correction and crosstalk correction data. When the set is switched on, the data is read to IC4601 (IXB001WJ). ∫ IC4901 (IXB002WJ) This is a QS (QuickShot) driver. QS drive is carried out for the input signal from the IC4601 (IXB001WJ) picture quality correction chip.
Page 45 LC-26GA5H/M/X ∫ IC2710 (NJU26150) The NJU26150 is a processor IC that is composed of DIR-incorporating 24-bit DSP (Digital Signal Processor) core and various interfaces. The program written on IC2708 (EEPROM) is downloaded to the built-in PRAM for operation. The built-in functions include audio delay, BBE, and parametric equalizer. Digital processing is made in the I2S format.
