Overview

a 200 MHz Clock Generator PLL ADF4001 FEATURES 200 MHz Bandwidth 2.
7 V to 5.
5 V Power Supply Separate Charge Pump Supply (VP) Allows Extended Tuning Voltage in 5 V Systems Programmable Charge Pump Currents 3-Wire Serial Interface Hardware and Software Power-Down Mode Analog and Digital Lock Detect Hardware Compatible to the ADF4110/ADF4111/ ADF4112/ADF4113 Typical Operating Current 4.
5 mA Ultralow Phase Noise 16-Lead TSSOP 20-Lead LFCSP GENERAL DESCRIPTION The ADF4001 clock generator can be used to implement clock sources for PLLs that require very low noise, stable reference signals.
It consists of a low noise digital PFD (phase frequency detector), a precision charge pump, a programmable reference divider, and a programmable 13-bit N counter.
In addition, the 14-bit reference counter (R counter) allows selectable REFIN frequencies at the PFD input.
A complete PLL (phase-locked loop) can be implemented if the synthesizer is used with an external loop filter and VCO (voltage contro...
