MAX9288/MAX9290
3.12Gbps GMSL Deserializers
for Coax or STP Input and MIPI CSI-2 Output
General Description
Benefits and Features
The MAX9288/MAX9290 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 CSI-2 outputs.
● Ideal for High-Definition Video Applications
• 4-Lane CSI-2 Output with Up to 1Gbps Per Lane
• Works with Low-Cost 50Ω Coax Cable and FAKRA
Connectors or 100Ω STP
• 104MHz High-Bandwidth Mode Supports
1920 x 720p/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
• CNTL0–CNTL3 Control Outputs for HDMI/MHL
The MAX9290 has HDCP content protection but other-
wise is the same as the MAX9288. The deserializers pair
with any GMSL serializer capable of coax output. 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
eight channels of L-PCM in TDM mode. Sample rates of
32kHz to 192kHz are supported with sample depth up to
32 bits.
● Multiple Data Rates for System Flexibility
• Up to 3.12Gbps Serial-Bit Rate
The embedded control channel operates at 9.6kbps
• 6.25MHz to 104MHz Pixel Clock
• 9.6kbps to 1Mbps Control Channel in UART, Mixed
2
to 1Mbps in UART-to-UART and UART-to-I C modes,

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 (MAX9290).
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.

UART/I C, or I C Mode with Clock-Stretch
Capability
● Reduces EMI and Shielding Requirements
• Tracks Spread Spectrum on Input
• High-Immunity Mode for Maximum Control-
Channel Noise Rejection
● Peripheral Features for System Power-Up and
Verification
For use with longer cables, the deserializers have a pro-
grammable cable equalizer. The serial input meets ISO
10605 and IEC 61000-4-2 ESD standards. The GMSL
supply is 3.0V to 3.6V, the MIPI CSI-2 supply is 1.7V to
1.9V, and the I/O supply is 1.7V to 3.6V.
• 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
The devices are available in lead(Pb)-free, 48-pin, 7mm
x 7mm 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
Applications
● High-Resolution Automotive Navigation
● Rear-Seat Infotainment
● Megapixel Camera Systems
• -40°C to +105°C Operating Temperature
•
8kV Contact and 12kV Air ISO 10605 and
IEC 61000-4-2 ESD Protection
