User Manual | PE11S100X Series Synthesizer 1.0 Applicable Products PE11S1001, PE11S1002 2.0 General Description This operating guide applies to the PE11S100X synthesizer modules operating up to 20 GHz output frequency. The purpose of this guide is to describe features common to all the synthesizer modules. The PE11S100X synthesizer modules contain phase locked loops consisting of various Pasternack die. -

If the synthesizer is in integer mode, a write to the integer frequency register, Reg 0Fh, will initiate the frequency hop on the falling edge of the 31st clock edge of the serial port write (see Figure © 2019 Infinite Electronics, Inc.

User Manual | PE11S100X Series Synthesizer 4.4 CW Sweeper Mode The internal PLL features a built-in frequency sweeper function, useful for test instrumentation, FMCW sensors, automotive radars, and other applications. Sweeper modes include: a. Single-Step Ramp Mode b. 1-Way Sweep Mode c. -

. Odd triggers will ramp in the same direction as the initial ramp, while even triggers will ramp in the opposite direction. The functions of the sweep parameters for two-way sweeps are shown graphically in Figure © 2019 Infinite Electronics, Inc. Pasternack is a registered trademark of Infinite Electronics, Inc. -
Page 12: Single Step Ramp Mode
User Manual | PE11S100X Series Synthesizer Figure 3. 2-Way Sweep Control via Trigger 4.4.3 Single Step Ramp Mode Single-step mode is selected by setting ramp_singlestep (Reg 14 h<6>). In this mode, a trigger is required for each step of the ramp. Single-step mode will function with either one-way or two-way ramps. The operation of single-step mode for a one-way ramp is shown graphically in Figure Figure 4. -

UP and DN pump mismatch. Phase noise in fractional mode is strongly affected by charge pump offset. In addition, reference spurs in both integer and fractional mode are affected by the offset. © 2019 Infinite Electronics, Inc. Pasternack is a registered trademark of Infinite Electronics, Inc. -

Maximum offset is 430 μA. (Reg As an example, if the main pump gain was set at 1 mA, an offset of 373 μA would represent a phase offset of about (392/1000)*360 = 133 degrees 4.5.4 Charge Pump Operation Near the Minimum &... -

User Manual | PE11S100X Series Synthesizer the pin is exclusively SDO. If automux is enabled, the pin switches to SDO when the RD function is sensed on the 1st rising edge of SCK. If lkd_to_sdo_always is set, then the pin LD is dedicated for Lock Detect only, and it is not possible to read from the synthesizer. -

Page 20: Lock Detect With Phase Offset
User Manual | PE11S100X Series Synthesizer Figure 9. Normal Lock Detect Window 6.4 Lock Detect with Phase Offset When operating in fractional mode the linearity of the charge pump and phase detector are more critical than in integer mode. The phase detector linearity is worse when operated with zero phase offset. Hence in fractional mode it is necessary to offset the phase of the reference and the VCO at the phase detector. -
