Introduction
The SiI9287B HDMI Port Processor with InstaPort Viewing Technology is the second generation of HDMI® devices that support the HDMI Specification.
With four HDMI inputs and a single output, the SiI9287B port processor enhances the functionality of digital TVs using single system on a chip (SoC) solutions with integrated HDMI receivers. The port processor provides a simple, low-cost method of retransmitting digital audio and video to give consumers a truly all-digital experience. Built-in backward compatibility with DVI 1.0 allows HDMI systems to connect to any DVI 1.0 source.

FEATUREs
The SiI9287B device brings cutting edge innovations, such as:
• InstaPort™ viewing technology that reduces port
   switching time to less than one second
• Enhanced cable equalization for long cable
   support, even at Deep Color resolutions that
   enables the SiI9287B device to work with noisy
   signals and many sources, making the sink devices
   highly interoperable
• Integrated EDID and CEC functions
• Improved ESD protection on all signals connected
   to the HDMI connector.
  
HDMI Inputs and Output
Four HDMI input ports and single output port support:
• HDMI, HDCP, and DVI compatibility
• TMDS™ cores run at 25–225 MHz
• Supports video resolutions up to 1080p, 60 Hz, 12-
   bit or 720p/1080i, 120 Hz, 12-bit.

Control Capability
• Consumer Electronics Control (CEC) interface
   incorporates an HDMI-compliant CEC I/O and an
   integrated CEC Programming Interface (CPI);
   these simplify design and lower cost and software
   overhead
• Integrated EDID and DDC support for 4
   HDMI/DVI ports and 1 VGA port with a 256-byte
   NVRAM shared between ports that loads into
   separate 256-byte SRAM for each of 5 ports
• Individual control of Hot Plug Detect (HPD) for
   each of the 4 HDMI/DVI ports
• TPWR (TMDS clock detect) output to help speed
   soft mute of audio while plugging and unplugging
   cables
• Controllable by the local I2C bus.

Power Management
• Flexible power management provides extremely
   low standby power consumption
• Standby power can be supplied from an HDMI 5-V
   signal or from a separate +3.3 V or 5 V standby
   power pin
• Port power only can be used to read EDID
• Single power 3.3-V source
• Integrated 5 V to 3.3 V Voltage regulator.

Package
• 72-pin, 10 mm x 10 mm, 0.5 mm pitch QFN
   package with enhanced ePad™.
