ACT3A11T (TCXO)
ACT3A11VT (VCTCXO)
ACT53T 4 (TCXO)
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.
