Zusammenfassung:A low voltage drive circuit (LVDC) includes a digital to analog input circuit to convert transmit digital data into combined analog outbound data, the transmit digital data has a data rate based on a host input clock, and a first portion of the combined analog outbound data has a first oscillation rate based on a first transmit channel clock and a second portion has a second oscillation rate based on a second transmit channel clock. The LVDC also includes a drive sense circuit to convert the combined analog outbound data into an analog transmit signal that is transmitted on a bus. The LVDC also includes a clock circuit to generate a transmit input clock to synchronize receiving the transmit digital data from a host, generate the first transmit channel clock based on the host input clock, and generate the second transmit channel clock based on the host input clock.
