Jitter Considerations in Serdes Systems

The most jitter sensitive application besides driving A-to-D converters are systems deploying a serial link using

Serializer and De-serializer implementation (e.g. 10 GigEthernet). To fully estimate the clock jitter impact on the

link budget requires to understand the transmit PLL bandwidth and the receiver CDR bandwidth. As can be seen

in Figure 38, the bandwidth of TX and RX is the frequency range in which clock jitter adds without any

attenuation to the jitter budget of the link. Outside of these frequencies, the SERDES link will attenuate clock

jitter with a 20 dB/dec or even steeper roll-off.
