TLC5946: TLC 5946 lacks a few signals. Can we run it?

Part Number: TLC5946

I'm trying to run the LED using the TLC 5946. In my controller, There is a lack of signal for TLC 5946. SIN, SCLK, XLAT, BLANK, but the signal is coming out. GSCLK, no MODE signal. Do you need the circuits you need to get out? I wonder how it's gonna run the TLC5946. I'll wait for a quick reply.

Hi,

As you can see from datasheet page 1, Typical Application Circuit is the circuit.

SIN, SCLK, XLAT, BLANK, and GSCLK are necessay and MODE is also necessary if you use both DC mode and GS mode.

Please help to click "Resolve" if the problem is solved.

Thanks.
Regards,
Kenneth

Thank you for your reply. I am curious. Is TLC5946 possible with only one DC mode? Do not you need GS MODE? What signals do TLC5946 need when using only DC MODE?
