| ■製品概要／Product Overview | |
| The CD15 is a versatile clock distribution module for clocks up to 15 GHz. Key features are: - single-ended and differential IO operation, - programmable reference clock divider, - synchronous clock start/stop, - broadband operation, - adjustable main clock output swing and delay, - single supply voltage, - PLL, crystal oscillator and 15 GHz VCO. |

| ■特徴／Key Features |
| Main purpose of the CD15 is driving and synchronizing multiple multiplexers, ADCs or DACs. The symmetrical clock input buffer allows for single ended as well as differential drive. Additional pins aim for offset measurement and adjustment. Two main clock output buffers can be adjusted from 0.3 to 1.2V single-ended swing and can be used either single-ended or differential. The phase of the main clock can be controlled in a 95 ps range. For synchronizing multiple chips, the main clock can be switched to static low and restarted synchronously. To provide clocks for FPGAs, a programmable reference divider (ratio 1:2 up to 1:896) with two differential output buffers is included. Finally, for using either the build in LC-tank 15 GHz VCO or controlling external VCO, a PLL with a fixed divide-by-512 ratio and a crystal oscillator buffer is built-in. |
