Hi all,

I used this design to try the fv-1 chip but there is no output signal at output pins.

The circuit is powered correctly, the oscillator is working at 32.768khz correctly.

Can someone tell me where can be the problem?

NOTE: R10, R12 and R14 are JUMPERS.

I have only had a quick glance over your schematic but notice pin 6 of the FV-1 has no connection. It should go to 3.3v
