ACT531VT- 4 VCTCXO (Clipped Sinewave)

The ACT531VT family is a range of VCTCXOs housed in a ceramic package with a metal lid and is seam

welded for good longer term stability. The pads are gold plated and the lid is grounded via the package to

assist with EMI reduction.

Applications

include Networking, Ethernet, Audio & Modem Clocks, Set Top Boxes, Phase Locked

Loops, Telecomms, Video Games & many Consumer Applications.
