Ok, thanks. I was so focused on the IRIG and 10 MHz parts I didn't think about the NTP function (which is what the unit is for after all).
BTW - I had some misinformation in my original post. The Abracon AOCJY1A is probably pin compatible with the TS2100 but it's not voltage compatible. The OCXO supply voltage on PC board pads is 12 not 5 volts. So unless I can get the same MTI 240 OCXO, then I'm looking at just putting one in the case somewhere and running wires to it. I'd prefer not to cut traces. Anybody know of an inexpensive OCXO that meets the following criteria? 10 MHz sine output 12V or 5V supply voltage (either will work since it will be installed off board) 5V EFC (TS2100 DAC is 0.5-4.5V) Small enough to fit in a 1U rack enclosure (the Morion MV89A is too tall) I'm not striving for perfection, just some that is significantly better than the stock TCXO. -Bob On 03/25/2011 02:11 AM, Hal Murray wrote: >> Not sure what the "precision" setting is for (it's currently -19). >> > That's probably for NTP.
