Hello,
I've been working on amplifying the clock signal of the Si5351A clock generator.
Observing on an Oscilloscope I see that it constantly puts out 3.3 Volts Peak to Peak square wave with:
+1.67 Volts at the top, and -1.67 Volts at the base.
I've connected it to an Octal Buffer/Line Driver, this one in particular:
https://www.digikey.com/en/products/detail/on-semiconductor/74AC244SC/149106I just cannot get the line driver to turn on. Input Voltage on the Datasheet says -.5 to Vcc to +.5V.
The datasheet also states that the ACT244 has TTL-compatible inputs.
So, is 1.67 Volts not a TTL level voltage? The goal is to power the Line driver at 5 Volts and enable the line driver just by using the clock voltage.
If I cannot get the clock generator to turn this line driver on, can anyone recommend a Line driver that will?
attached is my schematic on how I'm hooking it up.
thanks to all
