11.2.2 Detailed Design Procedure
11.2.2.1 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 (for example, 10 GigEthernet). Fully estimating the clock jitter impact
on the link budget requires an understanding of the transmit PLL bandwidth and the receiver CDR bandwidth. As
can be seen in Figure 50, 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.
Figure 50. Serial Link Jitter Budget Explanation
Example: SERDES link with KeyStone™ I DSP
The SERDES TX PLL of the TI KeyStone™ I DSP family (see SPRABI2) for the SRIO interface, has a 13 MHz
PLL bandwidth (Low Pass Characteristic, see Figure 50). The CDCM6208V2, pin-mode 27, was characterized in
this example over Process, Voltage and Temperature (PVT) with a low pass filter of 13 MHz to simulate the TX
PLL. The attenuation is higher or equal to 20 dB/dec; therefore, the characterization used 20 dB/dec as worst
case.
Table 38 shows the maximum Total Jitter(1) over PVT with and without Low Pass Filter.
