Notes

Taken as high when IN+ > IN–, and as low otherwise.

Capacitors are inserted between these pins and ground.

Output block ground. Connect to GND2.

Ground for circuits other than the output block.

Connect a small resistor between this pin and ground.

Set the maximum output current so that I OUT = 0.58/Rf.

Connect a capacitor between this pin and GND2.

Internal circuit power supply stabilization.

8 MHz max

7 kHz max

Connect a capacitor between this pin and GND2.

On when the PLL phase is locked. This pin is an open collector output.

PLL phase comparator output

Start on low.

Stop on high or open.

Pulse output following the FG Schmitt comparator.

This pin is an open-collector output.

A minimum amplitude of 400 mVp-p is required.

Connect a capacitor between this pin and GND2.
