FFA-FFC-PixelMateC to FFC Adapters#

Two small format boards (FFA-A/FFC and FFA-FFC/A) are available which adapt the PixelMateC MIPI CSI-2 connector to an unshielded Flat Flexible Cable (FFC) and back. This allows the connection of affordable and highly available FFC cabling in different lengths between the front-end and the receiver for evaluation purposes and as reference for integrated solutions on custom basis.

Figure: System Diagram of FFA-A/FFC and FFA-FFC/A inside the FSM Ecosystem.

As shown in the above figure, the integration takes place in form of two FFAs, adapting from PixelMateC to FFC and back. The boards only take care about signal routing from one to the other connector, signals pass through and stay unaltered.

Cabling

For the cabling, an unshielded standard 40 pin FFC cable with 0.5 mm pitch is required. For signal matching, a TOP to BOTTOM cable (like the Molex 0150200440 or 0150200446) must be used in-between both adapters.

Due to the reduction from 60 pins to 40 pins, a couple of signals were dropped from the PixelMateC layout. The following signals are not available when using the FFC cable:

RST1 (1)
Second I2C (2)
MCLK 1, 2, 3 (3)
GPIOs: 14, 15, 8, 17, 9, 10, 11 (7)
SLAMODE 1, 2, 3 (3)
Second MIPI CLK (2)
GND (2)

Regular single sensor setups in the FSM Ecosystem (native CSI-2 or converted from SLVS) do not use these signals and are not affected by missing signals. The complete pinout can be found in the following adapter-specific chapters.

The FFA-A/FFC40 board adapts the output of the front-end (FSM+FSA stack) to utilize an appropriate FFC cable. The pin count is reduced from 60 pins to 40 pins; signals stay untouched.
