Product Brief

SiI9251

Applications

PinnaClear^™Input Processor

• LCD, plasma and

projection DTVs

First input processor with Silicon Image’s patent-pending InstaPort™

instantaneous port switching technology

Key Features

The PinnaClear SiI9251 input processor gives manufacturers the flexibility to add new

features to their HDTV platforms quickly and cost-effectively. In addition to managing all

the input interfaces into the DTV, 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.

• Patent-pending

InstaPort technology

• Four HDMI 1.3 input

ports support MHL

• Four component or

RGB inputs

• 12-bit ADC for Deep

Color analog video

The highly integrated PinnaClear™ SiI9251

video input processor is the first multi-port

input processor for the high-end and mid-range

HDTV market. The SiI9251 features four HDMI

1.3 inputs that deliver Deep Color with 12 bits

of video at 1080p resolution and 60Hz. The

SiI9251 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 SiI9251 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). An additional 12-bit ADC is

integrated for SCART compatibility to overlay

RGB data over CVBS. This fully integrated AVI

includes an internal voltage reference and an

anti-alias filter with selectable cutoff frequencies.

The SiI9251 processor also integrates a data

slicer/decoder to capture VBI data services.

• Four S-Video and

five CVBS inputs

• Full SCART support

• 2-channel digital

audio up to 192KHz

• Integrated CEC

• Four integrated

EDIDs with NVRAM

for each HDMI port

The four HDMI input ports on the SiI9251 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 SiI9251-equipped DTV without a

dock or dongle, with auto discovery of HDMI

or MHL source devices in the hardware.

In support of the processor’s HDMI functional-

ity, the the SiI9251 input processor comes pre-

programmed with HDCP keys to simplify

manufacturing and provide the highest level of

HDCP key security. The chip includes a 256-

byte Extended Display Identification Data

(EDID) RAM block and support for Consumer

Electronics Control (CEC) over a single wire

bus. SiI9251 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.

The SiI9251 supports multiple audio formats

and all common audio sample rates up to

192kHz. Audio is available for output on an

S/PDIF port or an I²S port.
