Abstract: An accuracy in the data transfer rate of 0.25 % is required according to USB specifications. In order to generate a clock signal, which renders this accuracy possible, the invention enlists the use of a clock generator unit that operates without quartz. The inventive clock generator unit comprises a n internal clock generator (11), a pulse counter (17), which is connected to t he internal clock generator (11), a pulse number memory (18), and a pulse filte r (14). The pulse counter counts the number of the internally generated clock pulses between two pulses of the synchronization signal (16), which are transmitted according to the USB specification. The difference between the determined pulse number and a specified pulse number is evaluated and is use d for controlling the pulse filter (14) that suppresses pulses, thereby resulting in the generation of a stabilized clock signal (13).

Abstract: A circuit for detecting, whether a voltage difference is below a desired voltage difference comprises a voltage shift resistor, a current provider and a detection circuit. The current provider provides a current flowing through the voltage shift resistor such that the desired voltage difference across the voltage shift resistor is determined by a reference signal. The detection circuit is configured to compare a first voltage at a first input with a voltage at a second input to obtain a signal. The voltage shift resistor is coupled between a conductor for a second voltage and the second input, such that the voltage at the second input differs from the second voltage by the desired voltage difference, and wherein the detection circuit is configured to provide the signal, such that the signal indicates, whether the voltage difference between the first and the second voltage is below the desired voltage difference.

Abstract: In accordance with the USB specifications, an accuracy of 0.25% is required for the data transmission rate. To generate a clock signal that allows this accuracy, the invention uses a clock generator unit that does not require a crystal. The clock generator unit includes an internal clock generator, a pulse counter that is connected to the internal clock generator, a pulse number memory, and a pulse filter. The pulse counter counts the number of internally generated clock pulses between two pulses of the synchronization signal, which are transmitted in accordance with the USB specification. The difference between the ascertained pulse number and a nominal pulse number is evaluated and is used for controlling the pulse-suppressing pulse filter. This results in a stabilized clock signal.

Abstract: A voltage monitoring arrangement including a number of comparison devices, which corresponds to a prescribed number of voltage ranges, compares the value of an input voltage with a reference voltage and outputs a prescribed signal if the input voltage is within one of the prescribed voltage ranges. The voltage monitoring arrangement has a latch circuit which, when a latch signal is applied, establishes which voltage range the input voltage is currently in when the latch signal is applied, resulting in the arrangement having automatic voltage range reduction. The voltage monitoring arrangement has a monitoring unit which outputs a predetermined signal if the input voltage is outside the voltage range which exists when the latch signal is applied.
