7.3.2 Isolation Channel Signal Transmission

The AMC0x11S-Q1 uses an on-off keying (OOK) modulation scheme, as shown in Figure 7-1, to transmit the modulator output bitstream across the SiO2-based isolation barrier. The transmit driver (TX) as illustrated in the Functional Block Diagram transmits an internally generated, high-frequency carrier across the isolation barrier to represent a digital one. However, TX does not send a signal to represent a digital zero. The nominal frequency of the carrier used inside the AMC0x11S-Q1 is 480MHz.

The receiver (RX) on the other side of the isolation barrier recovers and demodulates the signal and provides the input to the fourth-order analog filter. The AMC0x11S-Q1 transmission channel is optimized to achieve the highest level of common-mode transient immunity (CMTI) and the lowest level of radiated emissions. The high-frequency carrier and RX/TX buffer switching cause these emissions.
