700MHz/350MHz, Crystal-to-3.3V LVPECL Frequency Synthesizer

The 8432-11 is a general purpose, dual output Crystal-to-3.3V Differential LVPECL High Frequency Synthesizer. The 8432-11 has a selectable TEST_CLK or crystal inputs. The TEST_CLK input accepts LVCMOS or LVTTL levels and translates them to 3.3V LVPECL levels. The VCO operates at a frequency range of 200MHz to 700MHz. The VCO frequency is programmed in steps equal to the value of the input reference or crystal frequency. Output frequencies up to 700MHz for FOUT and 350MHz for FOUT/2 can be programmed using the serial or parallel interfaces to the configuration logic.

Features

  • Dual differential 3.3V LVPECL outputs
  • Selectable crystal oscillator interface or LVCMOS/LVTTL TEST_CLK
  • TEST_CLK can accept the following input levels: LVCMOS or LVTTL
  • Maximum FOUT frequency: 700MHz
  • Maximum FOUT/2 frequency: 350MHz
  • VCO range: 200MHz to 700MHz
  • Parallel interface for programming counter and VCO frequency multiplier and dividers
  • RMS period jitter: 25ps (maximum)
  • Cycle-to-cycle jitter: 65ps (maximum)
  • Full 3.3V supply voltage
  • 0°C to 70°C ambient operating temperature
  • For replacement device use 8T48N222B-dddNLG
