General Description
The MAX9286 Gigabit multimedia serial link (GMSL)
deserializer receives data from up to four GMSL serial-
izers over 50Ω coax or 100Ω shielded twisted pair (STP)
cables and output data on four CSI-2 lanes. Each serial
link has an embedded control channel operating from
9.6kbps to 1Mbps in UART-UART, UART-I

mode. Using the control channel, a µC can program the
serializers, deserializer, and peripheral device registers at
any time, independent of video timing. A maskable broad-
cast write speeds programming of image sensor registers.
For use with longer cables, the deserializer has a pro-
grammable cable equalizer and programmable error
detection and correction. The serial input meets ISO
10605 and IEC 61000-4-2 ESD standards. The core sup-
ply is 1.7V to 1.9V and the I/O supply is 1.7V to 3.6V.
The device is available in lead(Pb)-free, 56-pin, 8mm x
8mm QFND and TQFN packages with exposed pad and
0.5mm lead pitch.
