GENERAL DESCRIPTION
The ADF4106-EP 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 phase frequency detector (PFD),
a precision charge pump, a programmable reference divider,
programmable A counter and B counter, and a dual-modulus
prescaler (P/P + 1). The A (6-bit) counter and B (13-bit) counter, 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 phase-locked loop (PLL) can be
implemented if the synthesizer is used with an external loop
filter and voltage controlled oscillator (VCO). Its very high
bandwidth means that frequency doublers can be eliminated in
many high frequency systems, simplifying system architecture
and reducing cost.
Additional application and technical information can be found
in the ADF4106 data sheet.
