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.
