Frequency Tuning Range (Voltage)

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.
