ADF4118YRUZ

Clock Generator 100MHz to 300MHz Input 200MHz Output 16Pin TSSOP Tube

Product Details

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.
