ACT3A11VT (VCTCXO)

The ACT3A11T/ VT family is a range of TC/ VCTCXOs housed in a through hole package and

provides a high frequency stability across a wide 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 and, whilst primarily developed for Telecommunications Applications, they have

been found to be very suitable for many other Networking, Ethernet, Audio & Modem Clocks, Set Top

Boxes, Phase Locked Loops, Video Games & many Consumer Applications.

Please note that all parameters can not necessarily be specified in the same device

In line with our ongoing policy of product evolvement and improvement, the above specification may be subject to change without notice
