description

The CDC337 is a high-performance, low-skew clock driver. It is specifically designed for applications requiring

synchronized output signals at both the clock frequency and one-half the 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 at 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 CDC337 is characterized for operation from –40°C to 85°C.
