6.3.3 Isolation Channel Signal Transmission

The AMC0136 uses an on-off keying (OOK) modulation scheme to transmit the modulator output bitstream across the SiO2-based isolation barrier. The transmit driver (TX) 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 AMC0136 is 480MHz.

Figure 6-2 shows the concept of the on-off keying scheme.
