ADF4117BRU

The ADF4117BRU is a PLL frequency synthesizer from Analog Devices, part of the ADF411x family. It integrates a low-noise digital phase frequency detector, precision charge pump, programmable reference divider, programmable A and B counters, and a dual-modulus prescaler (32/33). The device accepts CMOS/TTL inputs and provides a clock output. It operates at a maximum frequency of 1.2GHz with a minimum input frequency of 5MHz. The supply voltage range is 2.7V to 5.5V, and the operating temperature range is -40°C to 85°C. The charge pump output current is typically 4.5mA. The device includes an internal divider and supports differential input.

The ADF4117BRU is housed in a 16-TSSOP package (0.173", 4.40mm Width) with gull-wing leads for surface mount mounting. It is supplied in tube packaging. According to the manufacturer, this part is RoHS non-compliant.

Typical applications include base stations for wireless radio (GSM, PCS, DCS, CDMA, WCDMA), wireless handsets, wireless LANs, communications test equipment, and CATV equipment. The synthesizer can be used to implement local oscillators in upconversion and downconversion sections of wireless receivers and transmitters when combined with an external loop filter and VCO.
