The ANX9030 is a high‐performance, High Defini‐
tion Media Interface (HDMI) transmitter chip with
an advanced feature set offered only by Analogix
Semiconductor.
The ANX9030 is pin‐compatible with the SiI9030 yet
offers additional features and functionality and
lower power operation. It includes HDCP 1.2
(High‐Bandwidth Digital Content Protection) cir‐
cuitry with internal memory to store a unique HDCP
device key.
The device directly interfaces to the HDMI output
connector of an HDMI‐enabled digital video source,
such as a digital set‐top box, DVD player, or inte‐
grated Audio/Video receiver. It also includes other
HDMI connector functions such as the I2C interface
for the DDC (Display Data Channel) and the Hot
Plug Detection input.
The ANX9030 accepts digital video and audio in
many commonly used data formats, sample rates,
and bit resolutions. Video, audio, auxiliary, and con‐
trol data is packetized according to HDMI standards,
making the ANX9030 fully compatible with HDMI
receivers such as the ANX9011 and ANX9021.
The ANX9030 is offered in an 80‐lead TQFP package.

HDMI Transmitter
Overview
HDMI has become the industry‐standard interface for transporting digital video and audio between consumer
electronic equipment such as DVD players, A/V receivers and digital televisions. HDMI includes the HDCP
protocol to ensure protection from unauthorized duplication of copyrighted media content. The ANX9030 is
compliant with the latest HDMI 1.2 standard and it also supports the optional 1‐bit audio format for Super CD
applications. Unique ANX9030 features include Built‐in Self Test (BIST) for the video and audio streams and
programmable pre‐emphasis for each TMDS differential output.
Video data can be input to the ANX9030 in various 12‐bit or 24‐bit interface formats. Single or dual‐edge clock
latching is supported. Pixel rates up to 165 MHz enable video formats such as 1080p and WUXGA (1200 x 1920
at 60 Hz) with reduced blanking. HSYNC and VSYNC inputs are provided, or embedded sync can be detected
when using ITU.656 format. A DE input is also provided, or a DE blanking period can be generated internally
based on HSYNC timing and register settings. To comply with the 4:4:4 RGB output base level requirement of
HDMI, a 4:2:2 to 4:4:4 sample rate interpolation filter is included, as well as a YCbCr to RGB color‐space con‐
verter; either ITU.601 or ITU.709 color‐matrix coefficients can be selected.
Audio data can be input through the serial S/PDIF interface in the format of IEC60958 (uncompressed LPCM)
or IEC61937 (Dolby, DTS, etc.). Optionally, eight audio channels can be input through the four I2S interfaces, or
six channels of One Bit Audio through six 1‐bit audio interfaces. One Bit Audio supports DSD (Direct Stream
Digital) as used by Super Audio CD. Audio sample rates from 32 to 196 kHz are supported. In conformance
with the HDMI standard, the audio clock rate can be asynchronous with the video pixel clock. Timing informa‐
tion (N and CTS values) are sent in HDMI auxiliary packets, along with audio format information, to allow the
HDMI receiver to reconstruct the audio sample timing, data format and channelization.
The ANX9030 includes one HDMI transmitter (source) interface which is comprised of three TMDS data chan‐
nels and one TMDS clock channel. The ANX9030 features Analogix’ advanced low‐jitter clock synthesis PLL
architecture with firmware‐configurable output swing and pre‐emphasis for each TMDS channel, allowing sig‐
nal optimization for long (or lower quality) cables.
The HDMI interface also includes the DDC (Display Data Channel) interface, as required for the HDMI connec‐
tor, as well as the Hot Plug Detect (HPD) input.
The ANX9030 communicates with the system host micro controller through the dedicated host I2C control
interface. This enables the device to report media and link status, and allows device configuration and power
management. The I2C control interface is also used to read HDMI sink E‐DID data received through the DDC
link.
The HDCP encryption engine contains the encryption logic for all HDMI data (audio, video, and control).
HDCP encryption and authentication is performed automatically following device initialization. Pre‐pro‐
grammed HDCP keys and Key Selector Vectors (KSV) are stored in embedded ROM for the encryption
process. When using the ANX9030, system manufacturers do not need to purchase key sets from the Digi‐
tal‐Content LLC; the distribution and security of the HDCP keys are handled by Analogix.
