RF Clock IC provides fast output, high jitter

Analog Devices Inc.(ADI) has recently revealed its AD9525 RF clock IC. ADI's latest clock IC has an absolute broadband root-mean square (RMS) jitter of 83-fs (1kHz to 100MHz offset range), at 245.76MHz, including jitter contribution from the external voltage-controlled oscillator (VCO).

The device also supports up to a 3.6GHz output speed that the company claims 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 defence electronics where exceptionally clean clock synthesis is required for data conversion operations in the GSPS (billions of samples per second) range.

Other features include output-to-output skew 25 ps, number of outputs 8 LVPECL and 1 LVPECL SYNC, supply voltage: 3.3 V.
