The SiI9185A is the first generation of TMDS switch device supporting Revision 1.3 of the 
HDMI Specification (HDMI Consortium; June 2006). With three HDMI inputs and a single 
output, the SiI9185A provides a low-cost method of adding  additional HDMI ports to the 
latest Digital TVs.  New DTVs can  easily connect to the many  HDMI sources coming  on 
the market,  including  DVDs,  STB,  game  consoles,  PCs, camcorders,  and  digital  still 
cameras.  The  SiI9185A  is  a fully  HDMI  compliant  device  providing  a  simple,  lowcost
method  of  retransmitting  protected  digital  audio and  video,  giving  end-users  a  truly  all-
digital experience.  Built-in  backward  compatibility  with  DVI 1.0  allows  HDMI  systems  to 
connect  to  any  DVI  1.0 source. The  SiI9185A  provides  additional  integrated  features  to
help  lower  system  cost  and  provide  enhanced  features to  the  end  consumer.  To  lower 
system  cost,  the SiI9185A  provides  a  complete  solution  for  switching  sink-side  HDMI 
signals. This includes DDC switching, individual HPD control, and 5V sense. The addition 
of these  features  eliminates  additional  external components,  helping  to  lower  cost.  For 
source-side applications, the SiI9185A DDC switching can be bypassed with an external 
4-channel I2C-bus switch(e.g., Texas Instruments PCA95445) to allow clock
stretching.

 Three-input, single-output HDMI switcher

 Integrated TMDS® receiver and transmitt cores capable of receiving and 

transmitting 2.25 Gbps:

 Support 60 Hz, 12-bit or 720p/1080i, 120 Hz, 12-bit

 Builcable support even at deep-color resolutions

 Pre-emphasi

 DVI 1.0, HDCP 1.1 and HDM compliant receiver and transmitter

 Uses HDMI-compliant TMDS core recovery and retransmission, unlike TMDS 

switches, which use high-spee analog switches and degrade TMDS signals

 Built-in Cons support:

 HDM lowers cost for adding CEC support to DTV

 Integra requirements on system microcontrolle speeds design
