Ref: CYW20719 Data Sheet, Page 9, Recommended 24 Mhz Oscillator Configuration.
NOTE: The 24 Mhz crystal requires two external load capacitors.
The MLCCs are hard to source right now.
I want to replace the 24 Mhz crystal with an crystal oscillator with a LVCMOS output.
A. What is the logic level that I can use to drive the XIN? Is this a 1.5V, 1.8V, 2.5V or 3.3V?
B. What is the equivalent circuit capacitance? All clocks have a drive level spec, such as 15 pF, 30 pF, etc. If using
a clock, what is the drive level for the input?
C. How do I configure the clock output? Does it drive XIN or XOUT?
D. What do I do with the unused pin? XIN or XOUT depending on question C?
MLCCs are extremely difficult to source. I do not care about the added cost of an XO vs Crystal since I can not get capacitors
anywyas. I just need the 24 Mhz reference.
We have not tested using a LVCMOS output crystal oscillator with our chipsets. I am afraid we cannot recommend using it.
