ADF4113HV

Data Sheet High Voltage Charge Pump, PLL Synthesizer ADF4113HV FEATURES High voltage charge pump (15 V) 2.7 V to 5.5 V power supply 200 MHz to 4.0 GHz frequency range Pin compatible with ADF4110, ADF4111, ADF4112, ADF4113 ADF4106, and ADF4002 synthesizers Two selectable charge pump currents Digital lock detect Power-down mode Loop filter design possible with ADIsimPLL™ APPLICATIONS Applications using high voltage VCOs IF/RF local oscillator (LO) generation in base stations Point-to-point radio LO generation Clock for analog-to-digital and digital-to-analog converters Wireless LANs, PMR Communications test equipment GENERAL DESCRIPTION The ADF4113HV is an integer-N frequency synthesizer with a high voltage charge pump (15 V). The synthesizer is designed for use with voltage controlled oscillators (VCOs) that have high tuning voltages (up to 15 V). Active loop filters are often used to achieve high tuning voltages, but the ADF4113HV charge pump can drive a high voltage VCO directly ...
