ACT381T-4(6) ACT381VT-4(6) TCXO / VCTCXO(Clipped Sinewave)
The ACT381 family is a range of four and six pad TCXOs and VCTCXOs housed in a
Metal PCB based SMD package. In addition to this data sheet there is a separate
TCXO data sheet for a HCMOS/TTL version. It is therefore necessary to select the
output and the function to ensure that you receive the correct part. e.g. Clipped
Sinewave and TCXO or VCTCXO.
