    DUAL OUTPUT RF FREQUENCY SYNTHESIZER
    Application Information
    Power Supply Filtering Technique
    As in any high speed analog circuitry, the power supply pins are
    vulnerable to random noise. To achieve optimum jitter performance,
    power supply isolation is required. The ICS844S42I provides
    separate power supplies to isolate any high switching noise from the
    outputs to the internal PLL. VDD, VDDA, VDDOA and VDDOB should be
    individually connected to the power supply plane through vias, and
    0.01F bypass capacitors should be used for each pin. Figure 1
    illustrates this for a generic VDD pin and also shows that VDDA
    requires that an additional 10
    resistor along with a 10F bypass
    capacitor be connected to the VDDA pin.

    Recommendations for Unused Input and Output Pins
    Inputs:
    LVCMOS Control Pins
    All control pins have internal pullups or pulldowns; additional
    resistance is not required but can be added for additional protection.
    A 1k
    resistor can be used.
    Crystal Inputs
    For applications not requiring the use of the crystal oscillator input,
    both XTAL_IN and XTAL_OUT can be left floating. Though not
    required, but for additional protection, a 1k
    resistor can be tied from
    XTAL_IN to ground.
    REF_CLK Input
    For applications not requiring the use of the reference clock, it can be
    left floating. Though not required, but for additional protection, a 1k
    resistor can be tied from the REF_CLK to ground.
    Outputs:
    LVPECL Outputs
    All unused LVPECL outputs can be left floating. We recommend that
    there is no trace attached. Both sides of the differential output pair
    should either be left floating or terminated.
    LVDS Outputs
    All unused LVDS output pairs can be either left floating or terminated
    with 100
    across. If they are left floating, we recommend that there
    is no trace attached.
