Other Parts Discussed in Thread: TMS320F28035, TMS320F28030
Hi All,
May I know why TPS92661EVM-001 use an external clock for TMS320F28035?
Does it have any purpose to use external clock?
Can I use internal oscillators?

Hi Kevin,
From the product line:
As you may know, the TMS320F28035 has the following options for clocks: (Taken from the TMS320F28030 etc… data sheet)

Also from the data sheet, the zero-pin oscillator frequency varies with temperature. The communication between the TMS320 and the TPS92661 is accomplished with a UART which depends on a stable clock frequency. The variation that occurs with temperature of the zero pin oscillators will not meet the requirements for robust communications.
