MAX9276A/MAX9280A
3.12Gbps GMSL Deserializers
for Coax or STP Input and Parallel Output
General Description
The MAX9276A/MAX9280A gigabit multimedia serial link
(GMSL) deserializers receive data from a GMSL serializer
over 50Ω coax or 100Ω shielded twisted-pair (STP) cable
and output deserialized data on the LVCMOS outputs.
The MAX9280A has HDCP content protection but other-
wise is the same as the MAX9276A. The deserializers pair
with any GMSL serializer capable of coax output including
the MAX9293 HDMI/MHL serializer. When programmed
for STP input they are backward compatible with any
GMSL serializer.
The audio channel supports L-PCM I
2
S stereo and up to
eight channels of L-PCM in TDM mode. Sample rates of
32kHz to 192kHz are supported with sample depth up to
32 bits.
The embedded control channel operates at 9.6kbps
to 1Mbps in UART-to-UART and UART-to-I
2
C modes,
and up to 1Mbps in I
2
C-to-I
2
C mode. Using the control
channel, a µC can program serializer, deserializer, and
peripheral device registers at any time, independent of
video timing, and manage HDCP operation (MAX9280A).
Two GPIO ports are included, allowing display power-
up and switching of the backlight among other uses. A
continuously sampled GPI input supports touch-screen
controller interrupt requests in display applications.
For use with longer cables, the deserializers have a
programmable cable equalizer. Programmable spread
spectrum is available on the parallel output. The seri-
al input meets ISO 10605 and IEC 61000-4-2 ESD
standards. The core supply is 3.0V to 3.6V and the I/O
supply is 1.7V to 3.6V.
The devices are in lead-free, 56-pin, 8mm x 8mm TQFN
and SWTQFN packages with exposed pad and 0.5mm
lead pitch.
