Carrier frequency can be set by means of tying an external resistor to the F_SET pin, allowing a transmission from 125kHz up to 5MHz. Data rates are possible up to 500kbps depending on which carrier frequency was chosen. This is achieved by modulating the data at a higher frequency band (typically in the kHz and MHz band) on top of the power line. This reference design features a simple approach for PLC, using an On-Off-Keying modulator in combination with a line driver and passive filtering, to transmit data over. The PLC module supports solar technologies with modulation, adjustable frequencies, and built-in protections for stable, efficient functionality. Power Line Communication (PLC) is increasingly utilized across various end-equipment applications. In general, there are two categories, narrowband - and broadband - PLC., 50 Hz or 60 Hz depending on the region), reflects the balance. Carrier Frequency is the switching frequency of power components (IGBT/MOSFET) when a VFD generates PWM waveforms to control a motor.
