Sensor Extender

Functional Description

As previously noted, the Sensor Extender reference design consists of two devices. The MachXO2 device adjacent to the image sensor is referred to as the Tx device because it serializes the image data and transmits it across the CAT5e/6 cable. The other MachXO2 device, just before the ISP, is the Rx device it receives image data and deserializes it.

Sensor Extender Tx Device

The Tx device implements two primary functions see Figure First, the Tx device interfaces to the image sensor. The MachXO2 FPGA can be reprogrammed with Lattice’s many image sensor interface reference designs to provide numerous options. Lattice offers sensor interface bridges for Aptina HiSPi, Panasonic MN34041, Sony subLVDS and CSI-2 image sensors, all of which can be used with the Sensor Extender. These interface bridges convert the serial interface into a parallel data bus. The Sensor Extender can also directly interface to sensors that have parallel CMOS interfaces in this case no sensor interface bridge is needed.
