|Maxim's MAX9271 compact serializer is designed to drive 50 Ω coaxial or 100 Ω 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 a single input.
The device features an embedded control channel that operates at 9.6 kbps to 1 Mbps in UART and mixed UART/I²C modes, and up to 400 kbps 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/de-emphasis. 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 1.7 V to 1.9 V and the I/O supply range is 1.7 V to 3.6 V. The device is available in a 32-pin (5 mm × 5 mm) TQFN-EP package with 0.5 mm lead pitch and operates over the -40°C to +105°C temperature range.
