AD9552/PCBZ, Evaluation Board for Evaluating the AD9552 Oscillator Frequency Upconverter

Per contattare il Servizio Clienti.

• AD9552/PCBZ, Evaluation Board is a compact, easy to use platform for evaluating all features of the AD9552 oscillator frequency upconverter. The AD9552 is a fractional-N phase-locked loop (PLL) based clock generator designed specifically to replace high frequency crystal oscillators and resonators. The device employs a sigma delta modulator (SDM) to accommodate fractional frequency synthesis. The user supplies an input reference signal by connecting a single-ended clock signal directly to the REF pin or by connecting a crystal resonator across the XTAL pins. The AD9552 is pin programmable, providing one of 64 standard output frequencies based on one of eight standard input frequencies
