MAX9271
16-Bit GMSL Serializer with Coax or
STP Cable Drive
General Description
The MAX9271 compact serializer is designed to drive
50I coax or 100I shielded twisted-pair (STP) cable. The
device pairs with the MAX9272 deserializer.
The parallel input is programmable for single or double
input. Double input allows higher pixel clock input fre-
quency by registering two pixels of typical image-sensor
video data before serializing. This doubles the maximum
pixel clock frequency compared to single input.
The device features an embedded control channel that
operates at 9.6kbps to 1Mbps in UART and mixed UART/
I
2
C modes, and up to 400kbps in I
2
C mode. Using the
control channel, a microcontroller (FC) is capable of pro-
gramming serializer, deserializer, and camera (or any
peripheral) registers at any time, independent of video
timing. There is one dedicated GPIO, four optional
GPIOs, and a GPO output, allowing remote power-up of
a camera module, camera frame synchronization, and
other uses. Error-detection and correction coding are
programmable.
For driving longer cables, the device has programmable
pre/deemphasis. Programmable spread spectrum is
available on the serial output. The serial output 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 32-pin (5mm
x 5mm) TQFN-EP package with 0.5mm lead pitch and
operates over the -40NC to +105NC temperature range.
