Block Diagram


The TLSE is an improved high performance frequency synthesizer ideal for many SatCom, telecommunication and instrumentation applications.  This synthesizer’s frequency control is via standard industrial busses and has multi-drop capabilities. The input reference frequencies are either 5, 10 or 100 MHz.  Additionally, the synthesizer circuitry cleans-up the input reference signal.  With no input  present the unit switches automatically to the internal reference.

This design is field proven and has been deployed in critical applications throughout the world.  The TLSE offers excellent value providing great performance at a low cost
