产品概述
The CDC339 is a high-performance,
low-skew clock driver. It is specifically designed for applications requiring
synchronized output signals at both the primary clock frequency and one-half the
primary clock frequency. The four Y outputs switch in phase and at the same
frequency as the clock (CLK) input. The four Q outputs switch at one-half the
frequency of CLK. When the output-enable
(OE) input is low and the clear (CLR)
input is high, the Y outputs follow CLK and the Q outputs toggle on low-to-high
transitions of CLK. Taking CLR low asynchronously resets the Q
outputs to the low level. When OE is high, the outputs are in
the high-impedance state. The CDC339 is characterized for
operation from −40°C to 85°C.
