ICS8430-51

PRELIMINARY Integrated Circuit Systems, Inc. ICS8430-51 600MHZ, LOW JITTER LVCMOS/ LVTTL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER FEATURES Dual differential 3.3V LVPECL outputs Selectable crystal oscillator interface or LVCMOS/LVTTL TEST_CLK Maximum output frequency: 600MHz Crystal input frequency range: 14MHz to 25MHz VCO range: 200MHz to 700MHz Parallel or serial interface for programming counter and output dividers RMS period jitter: 2.6ps (typical) Cycle-to-cycle jitter: 17ps (typical) 3.3V supply voltage 0°C to 70°C ambient operating temperature Industrial temperature information available upon request GENERAL DESCRIPTION The ICS8430-51 is a general purpose, dual output ,&6 Crystal-to-3.3V Differential LVPECL High Frequency HiPerClockS™ Synthesizer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8430-51 has a selectable TEST_CLK or crystal inputs. The VCO operates at a frequency range of 200MHz to 700MHz. With FOUT0 configured to divide the VCO frequency by 2, output frequency steps as small as 2MHz can be achieved using a 16MHz crystal or reference clock. FOUT1 provides an additional divide by 16 and 180° phase shift. Output frequencies up to 600MHz can be programmed using www.DataSheet4U.com the serial or parallel interfaces to the configuration logic. The low jitter and frequency range of the ICS8430-51 make it an ideal clock generator for most clock tree applications. BLOCK DIAGRAM VCO_SEL XTAL_SEL TE...
