ICS8430-111

PRELIMINARY Integrated Circuit Systems, Inc. ICS8430-111 700MHZ, LOW JITTER DIFFERENTIAL-TO-3.3V LVPECL FREQUENCY SYNTHESIZER FEATURES Dual differential 3.3V LVPECL output Selectable 14MHz to 27MHz differential CLK, nCLK or TEST_CLK input CLK, nCLK accepts any differential input signal: LVPECL, LVHSTL, LVDS, SSTL, HCSL TEST_CLK accepts the following input types: LVCMOS, LVTTL Output frequency range up to 700MHz VCO range: 200MHz to 700MHz Parallel or serial interface for programming counter and output dividers Cycle-to-cycle jitter: 25ps (maximum) 3.3V supply voltage 0°C to 70°C ambient operating temperature Industrial termperature information available upon request GENERAL DESCRIPTION The ICS8430-111 is a general purpose, dual outICS put high frequency synthesizer and a member of HiPerClockS™ the HiPerClockS™ family of High Performance Clock Solutions from ICS. The CLK, nCLK pair can accept most standard differential input levels. The single ended TEST_CLK input accepts LVCMOS or LVTTL input levels and translates them to 3.3V LVPECL levels. The VCO operates at a frequency range of 200MHz to 700MHz. With the output configured to divide the VCO frequency by 2, output frequency steps as small as 2MHz can be achieved using a 16MHz differential or single ended reference clock. Outwww.DataSheet4U.com put frequencies up to 700MHz can be programmed using the serial or parallel interfaces to the configuration logic. The low jitter and frequency range of the I...
