... Note 2: Output rise and fall times are measured between the 10% and 90% of the V on lab bench characterization and is not tested in production. Note 3: Timing jitter is the ratio of the peak-to-peak variation of the period to the mean of the period. The specification is based on lab bench characterization and is not tested in production.

... Ground – Connect this pin to the system’s analog ground plane. 6 GND FOUT Programming Resistor Input. A 4.32MΩ resistor connected from this pin to GND sets the TS3002’s internal oscillator’s output period to 40μs (25kHz). For optimal performance, the 7 RSET composition of the RSET resistor shall be consistent with tolerances lower ...

... C is ~90kHz. be ≤7.5pF. operating TS3002 Start-up Time As the TS3002 is powered up, its FOUT terminal (and PWMOUT terminal, if enabled) is active once the applied VDD is higher than 0.9 volt. Once the applied VDD is higher than 0.9 volt, the master oscillator achieves steady-state operation within 1.2ms. ...

... Potentiometer to Trim the TS3002’s Output Frequency. Page 10 Using Standard Resistors to Increase FOUT Resolution The TS3002 can be configured to provide a 0.1% resolution on the output frequency as shown in Figure so, R1 can be set to approximately 10% of the value selected for R2. In addition, R2 and R1 should be chosen with a 0.1% and 1% tolerance, respectively ...
