What is the phase noise like on the cheap TCXO?Vectron
VT-702 (the first one in the list online)
-99 at 10Hz
-123 at 100Hz
-143 at 1kHz
going to Mouser and looking for the cheapest 10MHz TCXO
FOX924 (about $2) - no data
SiT5000 (about ) - -140 dBc@1kHz, -150 dBcfrom 10k to 100k, -160 @ 1M (no
price)
ECS -TXO-3225-100-TR ($2.71 each) - -135dBc @ 1 kHz
ASTX-H11 ($3.16) -130dBc @ 1 kHz, -158dBc @100k
FOX922CE at 16.369 MHz, -145 @ 10kHz
Can you provide a link to the "list online"?
I just went to digikey and searched for TCXO and 10 MHz
I am always wary when no or few specifications are provided. If you look at
manufacturer;s like Vectron, they provide lots of data, phase noise at many
frequencies, aging, etc.
it's what you pay for - if the spec says -135 at 10kHz, and that's all,
then that's what they test. - that's cheaper.
A $100 oscillator will tend to have a lot more data than a $2 one <grin>
At some point, you just BUY a batch of oscillators and test them yourself.
