A voltage controlled crystal oscillator,
with output logic levels compatible with
HCMOS and TTL logic families. The
device is packaged in a 6-pin, SMD, J
leaded package. The plastic molded sur-
face mountable package is ideal for to-
day'sautomatedassemblyenvironments.
This product family is compatible with
AT&T "S" series VCXOs.
