MAX9276A/MAX9280A
3.12Gbps GMSL Deserializers
for Coax or STP Input and Parallel Output
General Description
Benefits and Features
● Ideal for High-Definition Video Applications
• Works with Low-Cost 50Ω Coax Cable and FAKRA
Connectors or 100Ω STP
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.
• 104MHz High-Bandwidth Mode Supports
1920x720p/60Hz Display With 24-Bit Color
• Equalization Allows 15m Cable at Full Speed
• Up to 192kHz Sample Rate And 32-Bit Sample
Depth For 7.1 Channel HD Audio
• Audio Clock from Audio Source or Audio Sink
• Color Lookup Table for Gamma Correction
• CNTL[3:0] Control 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 S stereo and up to
● Multiple Data Rates for System Flexibility
• Up to 3.12Gbps Serial-Bit Rate
eight channels of L-PCM in TDM mode. Sample rates of
32kHz to 192kHz are supported with sample depth up to
32 bits.
• 6.25MHz to 104MHz Pixel Clock
• 9.6kbps to 1Mbps Control Channel in UART, Mixed
The embedded control channel operates at 9.6kbps

and up to 1Mbps in I C-to-I 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.
● Reduces EMI and Shielding Requirements
• Programmable Spread Spectrum Reduces EMI
• Tracks Spread Spectrum on Input
• High-Immunity Mode for Maximum Control-
Channel Noise Rejection
● Peripheral Features for System Power-Up and
Verification
• Built-In PRBS Tester for BER Testing of the Serial
Link
• Programmable Choice of 8 Default Device
Addresses
• Two Dedicated GPIO Ports
• Dedicated “Up/Down” GPI for Touch-Screen
Interrupt and Other Uses
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.
• Remote/Local Wake-Up from Sleep Mode
● Meets Rigorous Automotive and Industrial
Requirements
• -40°C to +105°C Operating Temperature
• ±8kV Contact and ±15kV Air ISO 10605 and
IEC 61000-4-2 ESD Protection
Applications
● High-Resolution Automotive Navigation
● Rear-Seat Infotainment
● Megapixel Camera Systems
