An integrated clock supply module for a memory module memory module, comprising the integrated clock supply component comprising, as well as a method for the operation of the memory module under test conditions

摘要

An integrated clock supply module (1) for a memory module,with a clock signal input (1.1) for applying a first clock signal (clk1) and a clock signal output (1.2 – 1.5),with a phase-locked loop (2), which on the input side to the clock signal input (1.1) is connected and for the generation of a second clock signal (clk2) serves,by means of a multiplexer (mux), via which the first clock signal (clk1) or the second clock signal (clk2) on the clock signal output (1.2, 1.5) is switchable,with a unit for frequency monitoring (3), which on the input side to the clock signal input (1.1) is connected and which is constructed and operated in such a way that, in the case of falling below a limit frequency (fmin) of the multiplexer (mux) is caused to the first clock signal (clk1) on the clock signal output (1.2, 1.5) to switch.
