MAX9280GTN/V+ Overview

IC DESERIALIZER

MAX9276/MAX9280
3.12Gbps GMSL Deserializers
for Coax or STP Input and Parallel Output
General Description
The MAX9276/MAX9280 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 MAX9280 has HDCP content protection but other-
wise is the same as the MAX9276. 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-UART and UART-I
2
C modes, and up to
1Mbps in I
2
C-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 (MAX9280). 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 pro-
grammable cable equalizer. Programmable spread spec-
trum is available on the parallel output. The serial 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-lead, 8mm x 8mm TQFN
and QFND packages with exposed pad and 0.5mm lead
pitch.
