ACT53T- 4 (TCXO)
ACT53VT- 4 (VCTCXO)
ACT53T-4 (TCXO)
The ACT53VT
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, WIFI, GPS & many Consumer Applications.
