Product Brief
SiI9185
VastLane HDMI Switch
3:1 HDMI 1.3 Switch with Integrated CEC Functionality
The VastLane SiI9185 is a Transition Minimized Differential Signaling (TMDS) switch that enables the connection of multiple High-Definition Multimedia Interface (HDMI) source devices to high-definition televisions (HDTVs). Based on the HDMI version 1.3 specification, SiI9185 is an advanced TMDS switch that delivers a cost-effective method
HDMI 1.3 with DDC
Applications
DTVs and HDTVs A/V receivers, HDMI switches and repeaters
Key Features
& HPD switching CEC support with CEC pin & API
for manufacturers to add additional HDMI ports to their HDTVs. Multiple HDMI ports allow consumers to connect a variety HDMI-enabled sources to their HDTVs. The SiI9185 is a three-to-one (3:1) switch ideally suited for use in the back panel of HDTVs and A/V receivers, allowing consumers to connect multiple HDMI-enabled devices such as highdefinition DVD players, set top boxes and game consoles. The SiI9185 switch selects a single HDMI or Digital Visual Interface (DVI) signal from the three HDTV receiver ports and generates fully compliant HDMI/DVI audio/ video output, as well as DDC/HDCP, HPD and +5V switching in full compliance with the HDMI and DVI specifications. The SiI9185 is among Silicon Images first generation of devices that integrate the Extended Display Identification Data (EDID). The EDID is stored in on-board RAM that is downloaded from the system microcontroller during power up or initialization. The EDID is reflected on each of the three HDMI ports thru the DDC bus. This allows elimination of up to three EDID ROMs, while also saving board space. The SiI9185 provides a complete, simple, solution to enabling Consumer Electronics Control (CEC) in a DTV. CEC is a single-wire bus that transmits remote control commands throughout a home network. The SiI9185 integrates both an HDMI compliant I/O and Silicon Image's CEC API. The CEC I/O meets all HDMI compliance tests and eliminates the need for additional external components, again saving board space and thereby significantly lowering the system level control by the microcontroller and simplifying firmware overhead.
Integrated EDID RAM Supports Deep Color Long cable support with built-in equalizer
