RF clock ICs with absolute broadband rms jitter of 83-fs at 245.76 MHz

Analog Devices, Inc. (ADI) has introduced an RF clock IC with 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). ADI claims the new RF clock IC supports up to a 3.6-GHz output speed that is nearly three times faster than competing clocks. The relevent applications for this IC includes instrumentation and defense electronics where exceptionally clean clock synthesis is required for data conversion operations in the GSPS (billions of samples per second) range and equipment that requires high-speed data conversion and optimum SNR (signal-to-noise ratio) performance.

Key Features of the AD9525 RF Clock IC:

RMS jitter:
83 fs @ 245.76 MHZ (1 kHz to 100 MHz)
46 fs @ 245.76 MHz (12 kHz to 20 MHz)
Maximum output speed: 3.6 GHz
Output-to-output skew: 25 ps
Number of outputs: 8 LVPECL and 1 LVPECL SYNC
Supply voltage: 3.3 V
