ACT3A01T (TCXO)
ACT3A01VT (VCTCXO)
The ACT3A01T/ VT family is a range of TC/ VCTCXOs housed in through hole packages, with various
height options, and provides for high frequency stabilities across a wide operating temperature and
supply voltage range. Parts are available with internal trimmer options and clipped sine / sine and square
wave outputs. The devices offer good reliability at a low cost and, whilst primarily developed for
Telecommunications Applications, they are also very suitable for many other Networking, Set Top Box,
Phase Locked Loops, Video Game & many Consumer Applications.
