TLC5970 Common 2-Wire Connected Differential Interface and next IC 4 wire possible?

Christian Voglhuber

Hi,

we are planing to use several ICs of TLC5970 PWM LED Driver in series.

The first IC will be controlled from a Microcontroller with Common 2-Wire Connected Differential Interface.

Can i use the 4 Wire Differential Interface at the output to connect to the next device or implies it that the output is also 2 wire mode?

The FUNCTIONAL BLOCK DIAGRAM in the datasheet describes the differential receiver and transmitter as converters, so am I right that it's possible to use 2 wire input and 4 wire differential output?

Thank you for any help.
