Hello,

Is it possible to use Non-synchronous internal clock mode for 953-914A connection in STP configuration?
if yes please tell me the setting.

It is not recommended to use non synchronous internal clock mode for backward compatibility mode.

Hello Carley,

Thank you for your answer. Could you tell me why it is not recommended? Is there any technical concern?

When operating 953 in backward compatibility mode, there's tight timing requirements.
See this app note www.ti.com/.../snla270a.pdf
The internal clock has a larger variance.
