Product Brief
SiI9261
VastLane
™
Input Processor
Input processor featuring full repeater support and Silicon Image’s
patent-pending InstaPort™ port switching technology
The VastLane SiI9261 input processor gives manufacturers the flexibility to add new fea-
tures to their A/V receiver platforms quickly and cost-effectively. In addition to managing
all the input interfaces, input processors offer innovations in legacy analog video inputs
with high-quality 12-bit state-of-the-art ADCs and AVI interfaces, new MHL™ interfaces
for HD mobile devices and InstaPort technology for faster port switching.
The highly integrated SiI9261 video input
processor is the first multi-port input processor
for the A/V receiver and wireless media box
market. The SiI9261 features four HDMI 1.3
inputs that deliver Deep Color with 12 bits of
video at 1080p resolution and 60Hz. The
SiI9261 also includes four analog high-definition
component video inputs that support YCbCr
and RGB formats and a 5-input composite and
4-input S-Video switch capable of selecting three
composite outputs or two Y/C outputs.
The four HDMI input ports on the SiI9261 sup-
port MHL, a low pin-count, low power interface
designed for mobile CE devices. MHL technol-
ogy enabled mobile devices can be connected
directly to an SiI9261-equipped A/V receiver
with auto discovery of HDMI or MHL source
devices in the hardware.
The SiI9261 analog video interface consists of
triple-channel 12-bit analog-to-digital converters
(ADCs) for capturing RGB and YPbPr inputs.
With conversion rates ranging from 12.5 MSPS
to 170 MSPS, the Analog Video Interface (AVI)
inputs capture 480i/576i to 720p/1080i/1080p
TV formats and PC graphic formats up to 1600
x 1200 (UXGA). This fully integrated AVI
includes an internal voltage reference and an
anti-alias filter with selectable cutoff frequencies.
The SiI9261 processor also integrates a data
slicer/decoder to capture VBI data services.
The SiI9261 supports multi-channel audio up to
7.1 channels and supports multiple audio for-
mats including high bit-rate (HBR) audio and all
common audio sample rates up to 192kHz.
Audio is available for output on an S/PDIF port
or an I
2
S port.
The SiI9261 input processor supports full
HDCP repeater functionality and comes pre-pro-
grammed with HDCP keys to simplify manufac-
turing and provide the highest level of HDCP
key security. The chip includes four 256-byte
Extended Display Identification Data (EDID)
RAM blocks and 256-byte NVRAM to store
EDID. The SiI9261 also supports Consumer
Electronics Control (CEC) over a single wire
bus. SiI9261 supports extremely low standby
power with power islands enabling CEC and
EDID operations when the device is in shut-
down mode consuming less than 35mW.
