... LOW JITTER, CRYSTAL-TO- 3.3V DIFFERENTIAL LVPECL FREQUENCY SYNTHESIZER General Description The ICS84330C is a general purpose, single output ICS high frequency synthesizer and a member of the HiPerClockS™ family of High Performance Clock HiPerClockS™ Solutions from IDT. The VCO operates at a frequency range of 250MHz to 700MHz. The VCO and output frequency can be programmed using the serial or parallel interfaces to the configuration logic ...

... VCO is scaled by a divider prior to being sent to each of the LVPECL output buffers. The divider provides a 50% output duty cycle. The programmable features of the ICS84330C support two input modes to program the M divider and N output divider. The two input operational modes are parallel and serial. Figure 1 shows the timing diagram for each mode ...

... Power Supply Filtering Technique As in any high speed analog circuitry, the power supply pins are vulnerable to random noise. To achieve optimum jitter perform- ance, power supply isolation is required. The ICS84330C provides separate power supplies to isolate any high switching noise from the outputs to the internal PLL. V ...
