Timing jitter measurement of 10 Gbps bit clock signals using frequency division

This paper presents a new method for measuring timing jitter of the bit clock signal in telecommunication devices operating at 10 Gbps. The method uses a divide-by-M circuit to reduce the frequency and the number of clock samples, and applies the Hilbert transform to measure the timing jitter The theory for this frequency division method is supported by the experimental data from a serializer-deserializer device.
