Product Brief
PinnaClear™ HDMI Receiver
Two-port HDMI 1.3 Compatible Receiver
• Plasma HDTV
The PinnaClear SiI9127 is a two-port HDMI receiver that delivers advanced HDMI 1.3
HDTV features including 1080p Deep Color and x.v.Color expanded color gamut. The
• Front and rear
projection HDTV
SiI9127 offers a cost-effective HDMI 1.3 solution with low standby power plus integrated
Key Features
CEC and EDID support.
• Two HDMI 1.3
The SiI9127 supports up to 36-bit color depth
at 1080p/60Hz, 720p/120Hz and 1080i/120Hz
resolutions and supports x.v.Color, which
increases the number of colors by 1.8 times the
RGB color space. The SiI9223 receiver also
includes a receiver programming interface that
significantly reduces the software overhead
required to control the receivers.
The SiI9127 integrates extended display identification data (EDID), which is stored in embedded non-volatile memory (NVM) and loaded
during power-up or initialization into two separate EDID RAMs. The two embedded EDIDs
simplify the architecture, help reduce BOM cost
and save board space.
Integrated consumer electronics control (CEC)
hardware and API help reduce BOM cost and
development time. The CEC I/O meets HDMI
compliance tests and eliminates the need for
additional external components. The CEC API
manages reception and transmission of all CEC
signals and significantly lowers system-level control by the system microcontroller, simplifying
firmware overhead.
The SiI9127 consumes a minimal amount of
power when in standby mode, with both CEC
and EDID remaining fully operational. The
standby power plane is isolated and can be powered locally from standby auxiliary power or
one of the +5V signals from the HDMI cable.
Additionally, only the +5V power from the
source device is needed to read the EDID and
the display can be completely unplugged from
the AC power outlet.
The SiI9127 comes pre-programmed with
HDCP keys. This set of keys simplifies the manufacturing process and lowers costs, while providing the highest level of HDCP key security.
The SiI9127 uses the latest generation of TMDS
core technology, supporting dynamic cable
equalization that will auto-detect the appropriate equalization required for the incoming signal, offering the best support for long cable
connections. Silicon Image TMDS cores pass all
HDMI compliance tests.
