Example For Chain With External LEDs

Several INLC10AQ devices can be daisy-chained

via 200Ω differential impedance lines to build up a chain

of external LED triplets. The communication between the µC and the first device is single ended.

The capacitive load that correlates with the cable or trace length of the connection between the first device

and the µC has to be minimized.

By switching off the phase shift, LEDs can be operated in parallel with two or three of the PWM outputs to

achieve higher output currents.

If the phase shift is switched off, all three channels are controlled symmetrically via the red PWM channel

(s. Figure 17). The phase shift can only be switched off for the complete daisy-chain. Therefore, a mixture

of RGB and single LEDs is not recommended.
