  • Page 57 2 、 HDMI switch ： SIL9185 The SiI9185A 3:1 HDMI 1.3 Switch is the first generation of TMDS switching devices that support Revision 1.3 of the HDMI Specification (HDMIConsortium; June 2006). With three HDMI inputs and a single output, the switch provides a low-cost method of adding additional HDMI ports to the latest digital TVs(DTVs).
  • Page 58 3 、 HDMI Receiver ： SIL9125 The SiI9125 is a second generation HDMI v1.3 with deep color outputs. Digital televisions that can display 10/12-bit color depth can now provide the highest quality protected digital audio/video over a single cable. The SiI9125 can receive deep color video up to 12-bit, 1080p@60Hz. Backward compatibility with DVI 1.0 allows HDMI systems to connect to existing DVI 1.0 hosts, such as HD set- top boxes and PCs.
  • Page 59 4 、 HDMI Hider:TMDS141 The TMDS141 HDMI hider is designed to accommodate a 1-m HDMI cable between a HDMI connector and a receiver. The internal cable causes signal distortion to high-speed TMDS signals, as well as increasing capacitance to the DDC channel. Each TMDS141 contains four TMDS repeaters to transmit digital content with signaling rates of up to 1.65-Gbps, and an I2C repeater to link extended display identification data (EDID) reading and high-bandwidth digital content protection (HDCP) key exchange under I2C standard mode operations.
  • Page 60 5 、 Video Filter : ADA4417-3 The ADA4417-3 is a low cost, fully integrated, video reconstruction filter specifically designed for consumer high definition video. With 1 dB frequency flatness out to 38 MHz, and 44 dB of rejection at 75 MHz, the ADA4417-3 can handle the most demanding HD video applications. The ADA4417-3 operates on a single 3.3 V to 5 V supply.
  • Page 61 6 、 Video Amplifier :ADA4759 ADA4859-3(triple) is a single-supply, high speed current feedback amplifier with an integrated charge pump that eliminates the need for negative supplies in order to output negative voltages or output a 0V level for video applications. The 195 MHz, large signal -3dB bandwidth at a fixed gain of 2, as well as the 740 V/us slew rate, make this amplifier ideal for high resolution professional and consumer video applications.
  • Page 62 7 、 Audio Power Amplifier : TPA3009D The TPA3009D2 is a 6-W (per channel) efficient, Class-D audio amplifier for driving bridged-tied stereo speakers. The TPA3009D2 can drive stereo speakers as low as 8 . The high efficiency of the TPA3009D2 eliminates the need for external heatsinks when playing music. Stereo speaker volume is controlled with a dc voltage applied to the volume control terminal offering a range of gain from –40 dB to 36 dB.
