SC16IS760 maximum baud rate

Martin10 — Fri, 18 Dec 2020 05:34:06 GMT

Dear Sir/Madam,

Based on the datasheet of SC16IS760, it states that the maximum baud rate this part can generate is 5 Mbps.

Also, from the datasheet I can see that the baud rate can be generated from the external crystal. I am wondering if there is a maximum crystal frequency that SC16IS760 can interface with? Would it work well with a 32 MHz crystal, just for example?

Thanks!

Please see datasheet page50-Table 38. fXTAL dynamic characteristics

I see. Thanks!

Another question on the load capacitance for the crystal. In figure 16, it shows that the two load capacitors used are different in the capacitance. However, in the past I typically see crystals with two capacitors with equivalent value.

Any particular reason to use two different capacitors in figure 16? Thanks!

No particular reason,you can use the same value.
