Clock Oscillator, CMOS, 3.3

Other Parts Discussed in Thread: AM3359

the data sheet on the Sitara AM3359 states LVC voltages and I assumed they were implying 3.3V, can you clarify. I am planning on using a clock oscillator, it is 3.3V, but CMOS output, not LVC, is that okay?

Hi Paul,

Section "4.2.2.2 OSC0 LVCMOS Digital Clock Source" of the datasheet states LVCMOS clock source. The input pin XTALIN is in the VDDS_OSC power domain, which is 1.8V, so external 1.8V oscillator should be used.

Best Regards

Yes, that is correct. I will add a power pin labeled with the respective AM335x power supply name to each LVCMOS clock block shown in this section of the data sheet.

Regards,
Paul
