"...Temperature stability is ±5 ppm within the -40°C to +85°C range,
which enables a highly accurate absolute time offset of 15 seconds over
the temperature range...."
I don't know that 5ppm is all that wonderful, considering I can get a
TCXO that is that good fairly easily, but it's much lower power..
They claim 6 microwatts to generate a 1pps.
I don't know how much they cost, but I suspect they're pretty inexpensive
The apnote at Petermann's website gives a fair number of specs (more
like a datasheet), but no timing performance.
They also don't say much about the DTCXO or how it works.
They're SW of Munich a bit past DLR Oberpfaffenhofen on the way to the
