Why does the DS2174 design kit (DS2174DK) have neither a crystal nor an oscillator?
A5. Because we do not know the customer’s working frequency domain, no crystal or oscillator is included in the DS2174DK. The DS2174DK does have an on-board selectable oscillator and an on-board selectable analog input for TCLK. The customer can use either a signal generator or an appropriate oscillator for TCLK.
