Description
●The MAX9271 compact serializer is designed to drive 50Ω coax or 100Ω 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 (µC) 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 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 × 5mm) TQFN-EP package with 0.5mm lead pitch and operates over the -40°C to +105°C temperature range.
