CMOS TTL Clock/Frequency Synthesizer (RF) 16-TSSOP (0.173 4.40mm Width) e0 clock generator circuit 5.5V 3GHz 5mm -40C~85C

The ADF4116/ADF4117/ADF4118 are frequency synthesizers which can be used to implement local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. They consist 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 (5-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). Control of all the on-chip registers is via a simple 3-wire interface. The devices operate with a 2.7V (± 10%) or 5V (± 10%) power supply and can be powered when not in use.
