ADF4110 Datasheet | Analog Devices

FEATURES GENERAL DESCRIPTION ADF4110: 550 MHz; ADF4111: 1.2 GHz; ADF4112: 3.0 GHz; ADF4113: 4.0 GHz 2.7 V to 5.5 V power supply Separate charge pump supply (VP) allows extended tuning voltage in 3 V systems Programmable dual-modulus prescaler 8/9, 16/17, 32/33, 64/65 The ADF4110 family of frequency synthesizers can be used to implement local oscillators in the upconversion and downconversion 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 Programmable charge pump currents (P/P + 1). The A (6-bit) and B (13-bit) counters, in conjunction Programmable antibacklash pulse width with the dual-modulus prescaler (P/P + 1), implement an N 3-wire serial interface Analog and digital lock detect Hardware and software power-down...
