MPC92433
Jitter Performance of the MPC92433
Figure 8 and Figure 9 illustrate the RMS jitter performance
of the MPC92433 across its specified VCO frequency range.
For some output dividers N, 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
MPC92433 output jitter decreases. Optimum jitter
performance can be achieved at higher VCO and output
frequencies.
For the output dividers of N=2, 4 and 6 the cycle-to-cycle
jitter does not depend on the VCO frequency. For the output
dividers of 2, 4 and 8 the period jitter does not depend on the
VCO frequency. 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 MPC92433 LVPECL outputs are designed to drive
50 transmission lines and require a DC termination to
VTT =VCC –2 V. Figure 10 illustrates the AC test reference
for the MPC92433 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
MPC92433 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 MPC92433 and supports clock frequencies
up to 300 MHz.
