The DeRTM-LOG1300, a MicroTCA.4 compliant LO and CLK generation module, has been successfully in operation at XFEL and FLASH for several years. With the company KVG Quartz Crystal Technology GmbH we started a collaboration in order to produce additional LO and CLK modules. At the same time, other machines require different LO and CLK frequencies. Not all of these frequency requirements can be covered with the present architecture. In the presentation we give a short overview of the current status and consider other possible LO and CLK generation techniques to provide frequencies required by other machines with different reference frequencies. In the second part of the contribution the KVG Quartz Crystal Technology GmbH will give a short overview of their activities.
