Overview
The ADF4106BRU-REEL7 from Analog Devices Inc. is a high-performance PLL (Phase-Locked Loop) frequency synthesizer designed for use in various wireless communication systems. It is particularly suited for implementing local oscillators in the up-conversion and down-conversion sections of wireless receivers and transmitters. The device features a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable reference divider, and programmable A and B counters along with a dual-modulus prescaler (P/P + 1).
