RF Clock IC Achieves Industry's Best Jitter Performance and Fastest Output Speed to Meet Demands of High-Speed Data Converters


Analog Devices, Inc. (ADI) today 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). The new RF clock IC supports up to a 3.6-GHz output speed that is nearly three times faster than competing clocks. The combination of high speed and low jitter is especially important for applications such as instrumentation and defense electronics where exceptionally clean clock synthesis is required for data conversion operations in the GSPS (billions of samples per second) range.

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
