Page 33: Major Ic Informations
LC-30HV4E MAJOR IC FUNCTIONS INFORMATIONS ∫ IC2501 (MSP4418G) IC for decoding audio signals. It serves as an S-IF audio signal decoder and an audio data selector. ∫ IC2510 (IXA385WJ) IC for controlling audio delay. LC-30/37HV4E uses a frame buffer to process video signals. This results in delay in outputting video signals.
Page 34 LC-30HV4E ∫ IC801/IC802 (TB1274AF) IC for synchronous processing of video and chroma demodulation for PAL/NTSC/SECAM colour TV. Color demodulation is provided by a high-performance image compensation circuit in the video section, a PAL/ NTSC/SECAM auto discrimination circuit in the chroma section, and a crystal that generates 4.43 MHz, 3.58 MHz and M/N-PAL clock signals.
