TLC5929: Timing Problem after first LED driver

Part Number: TLC5929

Tool/software:

Hi everyone,

hope anyone has an idea what the problem in my timing is.

We have an LED board with 72 TLC5929 drivers. After the first one, the data line is slightly shifted to the front. The attached picture shows the timing before the LATCH.
Data_1 represents the original data signal after the uC. Data_2 is the signal after the first LED driver (before the second) and so on.
It seems that the first driver shifts the signal forward. Does anyone have an idea how this can happen?

Many Thanks!

Best rehards,

Michael
