description
The CDC329 contains a clock driver circuit that distributes one input signal to six outputs with minimum skew
for clock distribution. Through the use of the polarity control inputs (T/C), various combinations of true and
complementary outputs can be obtained.
The CDC329 is characterized for operation from – 40°C to 85°C.
