3.6.1.1External Reference Oscillator Clock Option

The typical specifications for the external quartz crystal for a frequency of 20 MHz are listed below:

•Fundamental mode, parallel resonant

•CL (load capacitance) = 12 pF

•CL1 = CL2 = 24 pF

•Cshunt = 6 pF

•ESR range = 30 to 60 Ω

TI recommends that customers have the resonator/crystal vendor characterize the operation of their device with the DSP chip. The resonator/crystal vendor has the equipment and expertise to tune the tank circuit. The vendor can also advise the customer regarding the proper tank component values that will produce proper start up and stability over the entire operating range.
