[time-nuts] Fury Interface Board: How about TI OPA277?

[Brooke Clarke]

Hi Bruce:

The SC 10 can be configured with it's EFC voltage range the same as about any 
possible oscillator.  The PCB just has optional parts to allow that.

----------- from the above web page--------
Tuning
Mech. tuning range >±3 Hz
EFC range and slope
      Option 1 0 to 10 V, 5 V nominal, +0.5 Hz/V
      Option 2 0 to 10 V, 5 V nominal, -0.5 Hz/V
      Option 3 -10 to 10 V, 0 V nominal, +0.25 Hz/V
      Option 4 -10 to 10 V, 0 V nominal, -0.25 Hz/V
      Option 5 -5 to 5 V, 0 V nominal, +0.5 Hz/V
      Option 6 -5 to 5 V, 0 V nominal, -0.5 Hz/V
      Option 7 0 to 6 V, 3 V nominal, +0.75 Hz/V
      Option 8 0 to 6 V, 3 V nominal, -0.75 Hz/V

Have Fun,
