MAX9272
28-Bit GMSL Deserializer for Coax or STP Cable
General Description
Benefits and Features
S Ideal for Camera Applications
The MAX9272 compact deserializer is designed to
interface with a GMSL serializer over 50I coax or 100I
shielded twisted-pair (STP) cable. The device pairs with
the MAX9271 or MAX9273 serializers.
ꢀWorks with Low-Cost 50I Coax Cable and
FAKRA Connectors or 100I STP
ꢀError Detection/Correction
ꢀ9.6kbps to 1Mbps Control Channel in I2C-to-I2C
Mode with Clock Stretch Capability
ꢀBest-in-Class Supply Current: 90mA (max)
ꢀDouble-Rate Clock for Megapixel Cameras
ꢀCable Equalization Allows 15m Cable at Full
Speed
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.
The device features an embedded control channel that
operates at 9.6kbps to 1Mbps in UART and mixed UART/
I2C modes, and up to 400kbps in I2C mode. Using the
control channel, a microcontroller (FC) is capable of pro-
gramming serializer/deserializer and peripheral device
registers at any time, independent of video timing. Two
GPIO ports are included, allowing power-up and switch-
ing of the backlight in display applications and similar
uses. A continuously sampled GPI input supports touch-
screen controller interrupt requests.
ꢀ48-Pin (7mm x 7mm) TQFN-EP Package with
0.5mm Lead Pitch
S High-Speed Data Deserialization for Megapixel
Cameras
ꢀUp to 1.5Gbps Serial-Bit Rate with Single or
Double Output: 6.25MHz to 100MHz Clock
S Multiple Control-Channel Modes for System
Flexibility
ꢀꢀ9.6kbps to 1Mbps Control Channel in UART-to-
UART or UART-to-I2C Modes
For use with longer cables, the device has a program-
mable equalizer. Programmable spread spectrum is
available on the parallel output. The serial input meets
ISO 10605 and IEC 61000-4-2 ESD standards. The core
supply 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 -40NC to +105NC temperature range.
