It would seem that a simple diode from the 3.3 with a decoupling cap from the
2.4 side will do the job. The diode drop should remain fairly constant with a
reasonable current variance.

Hello,

I am using a motorola clock chip to generate
a # of differential clock signals to drive a
# of devices on my PCB. I want the Vcc of the
clock chip to be 2.4V. But the reference VDD
planes I have on the PCB are 1.9V & 3.3V.

What is the best way to generate the 2.4V for
the clock chip considering it's a very high
speed PCB ?

Thanks in advance.
