Comm Equip Makers Demand High Power Output & Small Footprint

Figure1. LTM4622(A) Can Be Mounted on the Underside of a PCB

Many communications systems are powered via a 48V backplane. This voltage is normally stepped down to a lower intermediate bus voltage, typically to either 12V, 5V or even lower, in order to power the racks of boards within the system. However, most of the sub-circuits or ICs on these boards are required to

Considerations When Selecting a Power Supply for Test Equipment

Figure 1: IEC61000 Selection Descriptions

When choosing a power supply, if an engineer had only to consider volts and amps, cooling requirements, size, and regulatory certifications, their job would be easy as there are many available options from which to choose. However, designers of test and measurement equipment must consider other important parameters.

Forward Error Correction (FEC) â€

Figure 1. Logic “0” to logic “1”, then back to logic “0”

In modern communication systems, information is digitised, coded to logic levels “1” and “0” and often further encoded into complex modulation schemes such as Pulse Amplitude Modulation (PAM) or Quadrature Amplitude Modulation (QAM).  Integrity of the information at the received end can be critical,
