Differential oscillators are commonly used in high-speed serial interface applications. This table shows several high speed serial data communications protocols, along with their line rates and reference clock frequencies. Also shown are the system jitter budgets and the integrated phase jitter for SiTime differential oscillators over the integration range for the standard. As an example, one implementation of 100 GbE is four channels (lanes) of 25.78125 Gb/sec of data transfer for an aggregate bandwidth of 103.125 Gb/sec. The most common reference clock frequency for a 25 Gb/sec link is 644.53125 MHz and the system jitter budget is 0.2 ps rms. The Elite Platform SiT936x oscillator supports this application with jitter that is significantly lower than the system budget at 0.061 ps over the integration range of 10 MHz to 40 MHz. These system jitter budget numbers and integration ranges are based on the governing standards such as IEEE 802.3 for Ethernet. The reference clock jitter is usually NOT explicitly specified in the governing standards. The usual rule of thumb is the reference clock is allocated 1/3 to 1/5 of the total system jitter budget.
