11.1 Layout Guidelines

The SDI, CLK, SDO, LE, and OE signals should all be kept from potential noise sources.

All traces carrying power through the LEDs should be wide enough to handle necessary currents.

All LED current passes through the device and into the ground node. There must be a strong connection between the device ground and the circuit board ground.
