EVALUATION KIT AVAILABLE
28-Bit GMSL Deserializer for Coax or STP Cable
General Description
The MAX9272A 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.
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. 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.
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 -40ºC to +105ºC temperature range.
