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.
