SiI9287B HDMI Port Processor with InstaPort Viewing Technology

Data Brief

.

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™.
