ACT3A04T (TCXO)
ACT3A04VT (VCTCXO)
ACT53T 4 (TCXO)
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.
