Analog Devices Inc. (ADI) introduced an RF clock IC, (radio frequency clock integrated circuit) with the industry’s lowest jitter for communications and instrumentation equipment that requires high-speed data conversion and optimum SNR (signal-to-noise ratio) performance. The AD9525 RF clock IC achieves absolute broadband rms (root-mean square) jitter of 83-fs (1-kHz to 100-MHz offset range), at 245.76 MHz, including jitter contribution from the external VCO (voltage-controlled oscillator).
