Other Parts Discussed in Thread: TPS65217
Hi,
I have a new prototype that uses TPS65910A3A1 and AM335x.
I found that the excitation of the main crystal starts only 2ms before the PORZ signal. See the attached screenshots.
I wonder if it's enough time to start and stabilize crystal (24MHz).
I've checked this time on the BBB and it's much longer >20ms.
The BBB uses TPS65217C.
yellow channel - PORZ (ZCZ - B15)
green channel - OSC0_OUT (ZCZ - U11)
Prototype
BBB
Is this 2ms time normal and intentional? Did I miss anything?
Why is this time 10 times longer in TPS65217?
BTW: I've already asked this question here
e2e.ti.com/.../3420546
I moved this question to the suggested forum.
