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

C, and I

C-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.
