ADF4153BRUZ

ADF4153 is a fractional-N frequency synthesizer that implements local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters. It consists of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. There is a Σ-Δ based fractional interpolator to allow programmable fractional-N division. A complete phaselocked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and a voltage controlled oscillator (VCO). A simple 3-wire interface controls all on-chip registers. The device operates with a power supply ranging from 2.7V to 3.3V and can be powered down when not in use. Typical applications are CATV equipment, base stations for mobile radio (GSM, PCS, DCS, WiMAX, SuperCell 3G, CDMA, W-CDMA), wireless handsets (GSM, PCS, DCS, CDMA, W-CDMA), wireless LANs, PMR, communications test equipment.

• INT, FRAC, and MOD registers define an overall N divider (N=(INT + (FRAC/MOD)))
• RF bandwidth to 4GHz, separate VP allows extended tuning voltage
• Programmable fractional modulus, programmable charge pump currents
• 3-wire serial interface, analogue and digital lock detect, power-down mode
• Pin-compatible with ADF4110/ADF4111/ADF4112/ADF4113 and ADF4106
• Consistent RF output phase, loop filter design possible with ADIsimPLL
• 4bit reference counter (R counter) allows selectable REFIN frequencies at the PFD input
• 16-lead thin shrink small outline package [TSSOP]
• Temperature rating range from -40°C to +85°C
