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 with a
passive-loop filter. The ADF4113HV can be used to implement
local oscillators in the upconversion and downconversion
sections of wireless receivers and transmitters. It consists of a
low noise digital phase frequency detector (PFD), a precision
high voltage charge pump, a programmable reference divider,
programmable A and B counters, and a dual-modulus prescaler
(P/P + 1).
A simple 3-wire interface controls all of the on-chip registers.
The devices operate with a power supply ranging from 2.7 V to
5.5 V and can be powered down when not in use.
