curve of the typical static phase error as a function of the free-
running oscillator frequency is shown in Figure 2. It should be
noted that the slope of the curve determines the DC gain of the
phase-locked loop, i.e., 40Hz per degree.
Thermal Considerations
The circuit of the CA3126 is thermally compensated to achieve
the optimal operating characteristics over the normal operating
temperature range of TV receivers. Figures 3 and 4 show the
oscillator and chroma-output amplitudes and phases as a func-
tion of temperature (Terminals 8 and 15), respectively.
Both the oscillator and chroma-output amplitudes and
phases are measured relative to the chroma-input phase.
The performance of the oscillator free-running frequency as
a function of temperature is shown in Figure 5. All the tem-
perature plots are characteristic of the test circuit with the
indicated component types and values given.
