Product Brief
The latest advances in video performance
require support of displays capable of 36-bit
color depth and up to 1080p resolution at 60Hz
or 720p/1080i resolution at 120Hz. Silicon
Image’s VastLane HDMI receivers meet these
demands and are ideal for rapid integration into
consumer electronics system architectures.
The SiI9125 is an advanced, dual-input HDMI
1.3 receiver that fits directly into digital televi-
sions such as LCD-TVs, plasma displays and
rear projection microdisplays (DLP, LCOS,
SXRD, D-ILA). The SiI9125 has two HDMI
input ports for connecting two HDMI 1.3
source devices such as HD-DVD or Blu-ray play-
ers or game consoles to an HDMI 1.3 enabled
HDTV.
The SiI9125 can receive 2-channel digital audio
up to 192 kHz. Compressed streams are also
supported through the S/PDIF port. An industry-
standard I2S port allows direct connection to
low-cost audio DACs at up to 192 kHz. An
S/PDIF port supports up to 192 kHz audio.
The built-in High-bandwidth Digital Content
Protection (HDCP) decryption engine secures
the digital link for transmission of valuable
high-definition video and audio. Each SiI9125 is
pre-programmed with unique HDCP keys, pro-
viding an extremely high level of security while
reducing manufacturing complexity and cost.
