A frequency divider circuit is disclosed with at least one push-pull
divider with adjustable division ratio and a connected converter device.
The circuit converts a clock signal delivered by a push-pull divider into
a single-ended signal. A first and a second single-ended divider are
connected to the output of the converter device, and a feedback path is
provided, which is connected to the output of the push-pull divider and
to the outputs of the first and of the at least one second single-ended
divider, and which includes an evaluation circuit. This circuit has first
and second inputs which are connected to the first and second
single-ended dividers in such a way that a future state of the clock
signal delivered by the single-ended divider in question can be supplied
to the inputs of the evaluation circuit. The evaluation circuit evaluates
states of the clock signals delivered by the first and second
single-ended dividers, i.e., states which will not exist until after
future switching functions have been performed. As a result, additional
time is gained for converting the signal to be divided from a push-pull
signal to a single-ended signal.
