Hello,
I removed the crystal and supplied CLKIN with a 16.384 Mhz square wave through a generator with peak 3.3V. I checked CLKOUT and it gives the inverse of the input signal as expected.
But the Ref voltage keeps low and the IRQ1 keeps high until I touch the CLKIN pin.
The IRQ1 goes low because of the body frequencies applied to it when I touch, it doesnt work continuously.
I tried with three IC, there cannot be anything wrong with the PCB. I ve attached the PCB design and the schematic in the first post.
Please help me to solve this issue. I tried with three different ICs.
Thank You
