ICS8432I-101

The ICS8432I-101 is a general purpose, dual output Differential-to-3.3V LVPECL high frequency synthesizer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8432I-101 has a selectable TEST_CLK or CLK, nCLK inputs. The TEST_CLK input accepts LVCMOS or LVTTL input levels and translates them to 3.3V LVPECL levels. The CLK, nCLK pair can accept most standard differential input levels. The VCO operates at a frequency range of 250MHz to 700MHz. The VCO frequency is programmed in steps equal to the value of the input differential or single ended reference frequency. The VCO and output frequency can be programmed using the serial or parallel interfaces to the configuration logic. The low phase noise characteristics of the ICS8432I-101 makes it an ideal clock source for Gigabit Ethernet and SONET applications.
