  5. DTV Tuner Audio Decoder Passive Components Back

  6. AKM • Audio Decoder • AK4388 (2CH, 192kHz) • Popular used in HDMI Input to convert Digital Signal to Analog Signal and then pass into Analog Audio Processor such as NJW1173, NJW1144, NJW1180, etc. • Major competitor : CS4334 (Cirrus Logic) • Audio Encoder • AK5358A (2CH, 128kHz) • It would be used in the design having Digital Audio Processor/Audio Delay or Highly Integrated Scalar which include Digital Audio Processing such as Zoran, MTK, etc. • Higher opportunity on DTV Design • Major competitor : CS5340 (Cirrus Logic)

  7. AKM • Audio Codec • AK4682 (Include Audio Switch), AK4555 (Generic Codec) • Cost down/Space Saving choice if the design is required to have Audio ADC & DAC • Main Advantage : 8 Stereo Inputs Selector & Digital Volume Control (AK4682) • Major competitor : CE2826 (CEI) • Audio Digital Interface Receiver/Transmitter (DIR/DIT) • AK4113, AK4114 • It would be used in the TV with SPDIF In/Out • Main Feature: Audio Format Detection (Non-PCM, DTS-CD, etc) • Higher opportunity on DTV Design

  8. AKM • Advanced Audio Codec • AK4683 (Include DIR/DIT) • More Cost effective choice as the design is required to have Audio Codec & Digital Audio Interface • Famous Design in DTV (AK4683 + NJW1173) • Major competitor : MSP34xx(Micronas), SGTV5800(Sigmatel) • BTSC Decoder • AK4140 (Audio ADC + BTSC Decode) • Focus on US Market (Standard is similar to Europe Nicam) • Main Advantage : Full Digital Process (Good Performance) • SCART Switch • AK4702/3/4 • Focus on Europe Market with SCART Connector Back

  9. NJRC SRS Processor See also ValenceTech • Audio Processor (BBE, SRS, Eala) • Sound Enhancement

  10. NJRC SRS Processor See also ValenceTech • Audio Processor (BBE, SRS, Eala) • Sound Enhancement

  11. NJRC • Headphone Amplifier • NJM2768/69A • Specially used in the design with ext. headphone required • NJM2777/NJM1109 • Good for the design with Picture-In-Picture • Audio Selector • Sometimes, LCDTV require to have more Audio Input (more than 8 inputs) • NJW1110 (9 Stereo Inputs,3 Outputs with Input Gain Adj.) • Video Amplifier • NJM2566 • Ambient Light Sensor (Analog Output) • NJL7502 • Low Cost one which can be also used in Digital Camera. • See also Vishay Product/Intersil Product Back

  12. muRata • Chip Ferrite Bead • BLM Series for use in HDMI • BLM18A/B Series on LVDS Connection • Chip Common Mode Choke Coils • DLP11S, DLP2AD, DLW21H Series for HDMI Use • DLM11G, DLM2HG Series for Audio Use • Chip EMI Filter • NFW31S, NFL21S Series • Used in Video Port such as CVBS, S-Video, RGB, etc for EMI Filtering

  13. muRata • NTC Thermistor • NCP Series on LCD Controller to monitor the temperature • Trimmer Potentiometers • PVZ2, PVZ3 Series for Screen Tuning with LCD Controller • Chip Multilayer Delay Line • LDH Series for Timing Adjustment
