EVALUATION KIT AVAILABLE MAX9273 22-Bit GMSL Serializer with Coax or STP Cable Drive General Description The MAX9273 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 frequency by registering two pixels of typical image-sensor video data before serializing. This doubles the maximum pixel clock frequ.

EVALUATION KIT AVAILABLE MAX9273 22-Bit GMSL Serializer with Coax or STP Cable Drive General Description The MAX9273 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 frequency 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/ I2C modes, and up to 400kbps in I2C mode. Using the control channel, a microcontroller (FC) is capable of programming 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 serializer 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 40-pin (6mm x 6mm) TQFN-EP package with 0.5mm lead pitch and operates over the -40NC to +105NC temperature range.
