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.
