Hi!
It is my first topic at EEEVblog. So Hello
![Smiley :)](https://www.eevblog.com/forum/Smileys/default/smiley.gif)
!
I have recently bought ocxo stable oscillator (for about 9$ - so worth it
![Smiley :)](https://www.eevblog.com/forum/Smileys/default/smiley.gif)
). It works fine, but there is no data sheet for this device.
Here is the ocxo photo:
http://img03.allegroimg.pl/photos/oryginal/48/76/94/72/4876947200The whole pcb is disassembled from GSM transmitter. Marking on it says:
PC9203 V255
RADIOSYSTEM
SWEDEN AB
TVM 351 131 R2
It has FPGA, uC and few memories. There are also connectors: BNC and SMB. So, I think the whole PCB is GPS disciplined oscillator.
I think circuit works (after suppling voltages leds are blinking). But without documentation this board is useless...
Can you help me finding DS for OCXO?
