Data input. There is no built-in amplifier on this pin.
Data outputs
RC oscillator input
This circuit generates a clock used to detect incorrect PLL locking and to reset the PLL system.
RC oscillator output
This pin outputs a clock with a frequency of about 40 kHz when the component values specified in the sample
application circuit are used.
CLKOUT2 output clock switching: Low = 256 fs, high = 128 fs
Clock mode switching: Low = 384 fs, high = 512 fs
Test pin (Should be tied low in normal operation.)
Used to start system operation after power is applied.
