ICM = International Crystal Manufacturing which has a website. Here's the
link: http://www.icmfg.com/tcxo.html#types
I ordered TCXO's based on required frequency of the crystal I was removing.
They are rectangular in shape and will require some spider leg type wiring
in as much as they will not fit in the footprint of the crystals coming out.
Also, you will need to wire Vcc (+5VDC) to the TCXO unit and add in a pot
from Vcc to ground and connect to the control pin Vc in order to adjust
frequency precisely. These units cost me about $40 each but if you want the
precision, this is the only way I've found to go.
