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

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.

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.
