How can i know that SC16IS740 Referenc circuit design?
i want to know reference design of SC16IS7XX series
and how to connect RS485 without transciever?
Can i connect directly RS 485 port to RXD, TXD?
Hi,
There is a Demo board kit using the SC16IS750 named OM6270, you can buy it directly from the following link: http://www.nxp.com/part/OM6270?lang_cd=en
Please find attached the schematics of this demo board that you can use as a reference for your circuit design.
Have a great day,
Jose

Hi Jose:
May I ask for advice for the OM6270 schematic?
I find the Xtal Y1 using 14.7465MHz in the schematic, but the datasheet of SC16IS0/750/760 show..1.8432MHz/3.072MHz.
Because Xtal 1.8432MHz/3.072MHz is going to EOL, I want to check that Is it ok to use 14.7465MHz ?
Thanks!
Samuel
Hi Samuel,
Yes, it is it ok to use 14.7465MHz, we have been using this crystal value in our boards and it works as expected.
Have a great day,

Hi Jose:
Thanks for your quickly reply,
It's helpful.
Another question.. that if I want to use 9600 baud rate by UART, may I use 12.288MHz xtal for this application?
best regards,
Samuel
