SiI9135/9135A HDMI Receiver with Enhanced Audio and Deep Color Outputs
Data Sheet
Silicon Image, Inc.
Overview
The SiI9135/9135A receiver can send and receive up to eight channels of uncompressed digital audio at 192 kHz and 2-
channel digital audio up to 192 kHz. Compressed streams are also supported through either the S/PDIF port or over I
2
S
for DTS-HD and Dolby TrueHD. An industry-standard I
2
S 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 device supports Super Audio Compact Disc (SACD) and
provides Direct Stream Digital (DSD) ports that support 44.1- and 88.2-kHz one-bit audio. Audio down-sampling allows
the receiver to share the audio bus with a high-sample-rate audio DAC while down-sampling audio for an attached
display that supports only lower rates.
The chip comes pre-programmed with High-bandwidth Digital Content Protection (HDCP) keys. This set of keys
simplifies the manufacturing process and lowers costs while providing the highest level of HDCP key security.
Silicon Image HDMI receivers use the latest generation of TMDS core technology. These cores pass all HDMI
compliance tests.
Unless otherwise specified, all mentions of the SiI9135 receiver in this datasheet also refer to the SiI9135A receiver.
