Jitter Performance of the MPC92432
Figure 8 and Figure 9 illustrate the RMS jitter performance
of the MPC92432 across its specified VCO frequency range.
The cycle-to-cycle and period jitter is a function of the VCO
frequency and the output divider N. The general trend is that
as the output frequency increases (higher VCO frequency
and lower N-divider) the MPC92432 output jitter decreases.
Optimum jitter performance can be achieved at higher VCO
and output frequencies. The maximum cycle-to-cycle and
period jitter published in Table 6 (AC characteristics)
correspond to the jitter performance at the lowest VCO
frequency limit. The VCO frequency can be calculated using
formula (2).
AC Test Reference and Output Termination
The MPC92432 LVPECL outputs are designed to drive
50 transmission lines and require a DC termination to
VTT =VCC –2V. Figure 10 illustrates the AC test reference
for the MPC92432 as used in characterization and test of this
circuit. If a separate termination voltage (VTT) is not available,
applications may use alternative output termination methods
such as shown in Figure 11 and Figure 12.
The high-speed differential output signals of the
MPC92432 are incompatible to single-ended LVCMOS
signals. In order to use the synthesizer in LVCMOS clock
signal environments, the dual-channel translator device
MC100ES60T23 provides the necessary level conversion.
The MC100ES60T23 has been specifically designed to
interface with the MPC92432 and supports clock frequency
up to 180 MHz.
