The CDC330 is a high-performance, low-skew clock driver. It is specifically designed for applications requiring output signals at both the primary clock frequency and one-half the primary clock frequency. This device contains two banks that fan out one input to three same-frequency outputs and one bank that fans out one input to four half-frequency outputs with minimum skew for clock distribution. Each bank of Y outputs switch in phase and at the same frequency as its clock (A) input. The four Q outputs switch at one-half the frequency of their clock (2A) input. When the output-enable (2OE) input is low and the preset (PRE) input is high, the Q outputs toggle on high-to-low transitions of 2A. Taking PRE low asynchronously presets the Q outputs to...
The CDC330 is a high-performance, low-skew clock driver designed for applications requiring output signals at both the primary clock frequency and one-half the primary clock frequency. It contains two banks: one to fan out a single input to three same-frequency outputs and another to fan out one input to four half-frequency outputs with minimum skew.
| Operating temperature range | 0°C to 70°C |
|---|---|
| High-level output current | -32 mA |
| Clock frequency (1A/3A) | 67 MHz |
| Clock frequency (2A) | 100 MHz |
The device features low output skew and low pulse skew.
The device distributes one clock input to three same-frequency outputs and another bank that fans out one input to four half-frequency outputs.
The device operates with a supply voltage between 4.75 V and 5.25 V.
Unused input or I/O pins must be held high or low to function correctly.
