Description
The ADF4106/7/8 frequency synthesizer can be used to implement the local oscillator in the upconversion and downconversion sections of the wireless receiver and transmitter. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, programmable A and B counters, and a dual mode prescaler (P/P+1). The A (6-bit) and B (13-bit) counters are combined with a dual-mode prescaler (P/P+1) to implement the N divider (N = BP + A). In addition, the 14-bit reference divider (R divider) allows the REFIN frequency at the PFD input to be selectable. If the frequency synthesizer is used with an external loop filter and voltage controlled oscillator (VCO), a complete phase-locked loop (PLL) can be implemented. Its high bandwidth allows many high frequency systems to eliminate the frequency multiplier, simplifying system architecture and reducing costs.
The ADF4106-EP supports defense and aerospace applications (AQEC standards).
