The 843034-06 is a general purpose, low phase noise LVPECL synthesizer which can generate frequencies for a wide variety of applications. The 843034-06 has a 4:1 input multiplexer from which the following inputs can be selected: one differential input, one single-ended input, or one of two crystal oscillators, thus making the device ideal for frequency translation or frequency generation. The 843034- 06 has dual LVPECL outputs that may be programmed for ÷2, ÷4 or ÷5 of the VCO frequency. The 843034-06 also supplies a buffered copy of the reference clock or crystal frequency on the single-ended REF_OUT pin which can be enabled or disabled (disabled by default). The output frequency can be programmed using either a serial or parallel programming interface. This device supports Spread Spectrum Clocking (SSC) for EMI reduction.
