6.6 HDMI Receiver (ANX9021)
The ANX9021 is an advanced multimedia receiver compliant with High Definition Multimedia
Interface (HDMI) Specification 1.2. HDMI is the first transport standard to unify digital video, audio,
and control da ta over lowcost cables. It connects digital television, flat panel displays and project
systems digitally to multimedia sources: DVD players, high definition settop boxes, digital video tape
recorders, and personal computers.Digital transmission, in turn, delivers an uncompromising multimedia
experience.
HDMI also i ncludes encryption for premium contents pursuant to the HighBandwidth Digital
Content Protection (HDC P) standard. The ANX9021 embeds the HDCP keys and key selection vectors
to reduce manufacturing co mplexity and system cost.
The ANX9021 receives two HDMI data streams and decodes the selected input into digital audio
and vide
o data outputs. The receiver incorporates Analogix’s proprietary WideEye™ architecture, which has
receiv ed considerable industry acclaim when introduced in Analogix’s 6.25 Gbps SerDes products for
telecom a nd datacom applications. Applying the same advanced techniques in ANX9021 allows
displays systems to achieve errorfree HDMI reception over long, inexpensive cables up to 20 meters and
assure the widest ran ge of interoperability against uncertain qualities of cheap cables from lowcost
suppliers as the standard ma tures.
The ANX9021 can receive and output up to eight digital audio channels at up to 192 kHz sampling
rate, m aking it the leading component for integrated home theaters and high definition televisions. The
device sup ports direct connections to a wide selection of audio DACs and decoders through industry
standard I2S or S/PDIF interfaces. The ANX9021 is offered in 144-lead TQFP lead-free packages.
