Quad 1.5Gbps GMSL Deserializer with Coax or STP Input and CSI-2 Output

 

Part Number	Replacement	Explanation

Description

Create a design and simulate using EE-Sim^® tools:

The MAX9286 Gigabit multimedia serial link (GMSL) deserializer receives data from up to four GMSL serializers 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-to-UART, UART-to-I²C, and I²C-to-I²C 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 broadcast write speeds programming of image sensor registers.

For use with longer cables, the deserializer has a programmable cable equalizer and programmable error detection and correction. The serial input meets ISO 10605 and IEC 61000-4-2 ESD standards. The core supply 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 × 8mm SWTQFN and TQFN packages with exposed pad and 0.5mm lead pitch.
