GENERAL DESCRIPTION
The ADF4107 frequency synthesizer 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 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.
