Fa

The ACT3A04T/ VT family is a range of low frequency TC/ VCTCXOs housed in through hole

packages, with various height options, and provides for tight frequency stabilities across a wide operating

temperature and supply voltage range. Parts are available with internal trimmer options. The devices offe

good reliability at a low cost and, whilst primarily developed for Communications Applications, they are

also very suitable for many other applications including Instrumentation, Phase Locked Loops, Video

Game & many Consumer Applications.
