The ADF420x family of dual frequency synthesizers are usedto implement local oscillators in the upconversion and downconversionsections of wireless receivers and transmitters. Eachsynthesizer consists of a low noise, digital, phase frequency detector(PFD); a precision charge pump; a programmable referencedivider; programmable A and B counters; and a dual modulusprescaler (P/P + 1). The A (6-bit) and B (11-bit) counters, inconjunction with the dual modulus prescaler (P/P + 1), implementan N divider (N = BP + A). In addition, the 14-bit referencecounter (R counter) allows selectable REFIN frequencies at thePFD input. The on-chip oscillator circuitry allows the referenceinput to be derived from crystal oscillators.
A complete phase-locked loop (PLL) can be implemented if thesynthesizers are used with an external loop filter and voltagecontrolled oscillators (VCOs).
Control of all the on-chip registers is via a simple 3-wireinterface. The devices operate with a power supply rangingfrom 2.7 V to 5.5 V and can be powered down when not in use.
