GENERAL DESCRIPTION
The ADF4107 frequency synthesizer can be used to implement
local oscillators in the up-conversion and down-conversion
sections of wireless receivers and transmitters. It consists of a
low-noise digital PFD (phase frequency detector), a precision
charge pump, a programmable reference divider, programmable
A and B counters, and a dual-modulus prescaler (P/P + 1). The
A (6-bit) and B (13-bit) counters, in conjunction with the dual-
modulus prescaler (P/P + 1), implement an N divider
(N = BP + A). 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 controlled oscillator). Its very high bandwidth means
that frequency doublers can be eliminated in many high
frequency systems, simplifying system architecture and
reducing cost.
