Analog Devices announced their AD9525 radio frequency clock integrated circuit. The AD9525 RF clock IC offers 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 ADI chip is available now for $8.33 each (1000 quantity) in 48-lead LFCSP packaging. The AD9525 RF Clock complements ADI’s high-speed data converter portfolio.
The AD9525 RF clock IC features 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). The new RF clock IC supports up to a 3.6-GHz output speed, which is almost three times faster than competing clocks.
The AD9525 radio frequency clock integrated circuit is ideal for instrumentation and defense electronics where exceptionally clean clock synthesis is required for data conversion operations in the GSPS (billions of samples per second) range.
