ACT381T- 4 & 6 TCXO (HCMOS/TTL)
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 / VCTCXO data
sheet for a clipped sine wave 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.
