Product Brief
SII9251
PinnaClearTM Input Processor
First input processor with Silicon Image's patent-pending InstaPortTM instantaneous port switching technology
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 MHLTM interfaces for HD mobile devices and InstaPort technology for faster port switching. The highly integrated PinnaClearTM 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 four HDMI input ports on the SII9251 support MHL, a low pin-count, low power interface designed for mobile CE devices. MHL technology 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. 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. 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. In support of the processor's HDMI functionality, the the SII9251 input processor comes preprogrammed with HDCP keys to simplify manufacturing and provide the highest level of HDCP key security. The chip includes a 256byte 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 shutdown mode consuming less than 35mW.

InstaPort technology dramatically reduces the wait time when switching between HDMI sources by performing background HDCP authentication with all source devices connected to the DTV. Since the authentication process is done on all ports simultaneously, when a new input is selected by the viewer it can begin streaming content immediately without waiting for HDCP authentication. As consumers continue to connect an increasing number of devices to their DTVs--from DVD players and game consoles to PCs and set top boxes--switching between them with limited delay becomes an increasingly desired feature.
