Hi,

 

I have 2 problems about the IC chosen and circuit.

 

1)

I want to do a PSK modulation/demodulation.

 

The carrier frequency is 14KHz.

 

Which modulator IC I can use?

 

Have any application note?

 

2)

I am looking for a constant current source.

 

The current is 0.03mA.

 

Have any application note?
