When I bought this elderly 34310-T, the seller (in China) said the midpoint EFC was about 4 volts. When I installed it, it was actually just under 3, which was a bit of a surprise. Just before my frequency glitch/drop, it was just a bit above 2.94. Now, the midpoint is just above 2.90. This thing gets a LOT of power cycles, as I swap each newly changed PIC into the PLL. I've noticed it go lower by a bit more than a millivolt over the past few days. Could these power cycles have something to do with the midpoint heading lower, or is this just a random direction/random movement? I will note that the VRef output on this oscillator is just below 6 Volts, if that means anything. Just trying to understand anything that's understandable about this.
