MAX9240A
6.25MHz to 100MHz, 25-Bit GMSL Deserializer for
Coax or STP Cable with Line Fault Detect
General Description
Benefits and Features
● Ideal for Camera Applications
• Works with Low-Cost 50Ω Coax Cable and FAKRA
Connectors or 100Ω STP
The MAX9240A compact deserializer is designed to
interface with a GMSL serializer over 50Ω coax or 100Ω
shielded twisted-pair (STP) cable. The device pairs with
the MAX9271 or MAX9273 serializers.
• Error Detection/Correction
• 9.6kbps to 1Mbps Control Channel in I C-to-I C
Mode with Clock Stretch Capability
• Best-in-Class Supply Current: 90mA (max)
• Double-Rate Clock for Megapixel Cameras

The parallel output is programmable for single or double
output. Double output strobes out half of a parallel word
on each pixel clock cycle. Double output can be used with
GMSL serializers that have the double-input feature.

Cable Equalization Allows 15m Cable at Full Speed
The device features an embedded control channel that
operates at 9.6kbps to 1Mbps. Using the control chan-
nel, a microcontroller (µC) can program the serializer/
deserializer and peripheral device registers at any time,
independent of video timing. Two programmable GPIO
ports and a continuously sampled GPI input are available.
• 48-Pin (7mm x 7mm) TQFN-EP Package with
0.5mm Lead Pitch
● High-Speed Data Deserialization for Megapixel
Cameras
• Up to 1.5Gbps Serial-Bit Rate with Single or
Double Output: 6.25MHz to 100MHz Clock
For use with longer cables, the device has a program-
mable equalizer. Programmable spread spectrum is avail-
able on the parallel output. The serial input meets ISO
10605 and IEC 61000-4-2 ESD standards. The core sup-
ply range is 1.7V to 1.9V and the I/O supply range is 1.7V
to 3.6V. The device is available in a 48-pin (7mm x 7mm)
TQFN-EP package with 0.5mm lead pitch and operates
over the -40°C to +105°C temperature range.
● Multiple Control-Channel Modes for System Flexibility
• 9.6kbps to 1Mbps Control Channel in UART-to-
2
UART or UART-to-I C Modes
● Reduces EMI and Shielding Requirements
• Programmable Spread Spectrum on the Parallel
Output Reduces EMI
• Tracks Spread Spectrum on Serial Input
● Peripheral Features for Camera Power-Up and
Verification
Applications
● Automotive Camera Systems
• Built-In PRBS Checker for BER Testing of the
Serial Link
