Evaluation Kit Configuration
The PE3336 Evaluation Board is configured with an on-board VCO, TCXO reference and
a second order active loop filter. The loop filter is followed by a low pass filter after the
Op Amp. The VCO tuning range is 3000 MHz to 3500 MHz and the reference oscillator
runs at 10 MHz. The active loop filter is designed for a 1 MHz comparison frequency and
a 3000 MHz output frequency with unity gain crossover at 75 kHz, phase margin of 65
degrees and 1.2 dB of peaking. The data provided was measured in this configuration
with the default jumper settings shown in Figure 2.
Two jumpers (JP1 & J3) configure the Evaluation Board to operate with either the on-
board reference oscillator (TCXO) or an external reference applied to J10. Figure 2
shows the proper configuration for utilizing the TCXO reference. JP1 in the middle-to-
right connection as shown connects the output of the TCXO to the PLL F
input, while J3
R
installed provides power to the TCXO. Do not connect any external reference to J10 if
the on-board reference is selected.
Figure 3 displays the proper configuration for
utilizing an external reference source. JP1 is in the middle-to-left connection, which
connects the PLL F
input to the J10 SMA connector and the jumper on J3 is removed to
R
power-down the TCXO.
The PE3336 Evaluation Kit also allows for manual programming using the fifteen on-
board switches. Setting the BMODE Control switch ON (BMODE switch S3-1) enables
direct mode programming. Setting the BMODE Control switch to the OFF position (S3-1)
and the A3-S_mode switch to the ON position (S3-8) the serial programming mode is
enabled allowing for software control.
The default jumper and switch settings are shown in Figure 2, which will place the part
into serial programming mode utilizing the on-board reference. Peregrine Semiconductor
recommends that the default settings be used initially to bring up the evaluation board
and duplicate the enclosed measured data.
