Product Brief

ANX9030

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.
