8.3.3 Isolation Channel Signal Transmission
The AMC1306 device uses an on-off keying (OOK) modulation scheme to transmit the modulator output bitstream across the capacitive SiO2-based isolation barrier. The transmitter modulates the bitstream at TX IN in Figure 49 with an internally-generated, 480-MHz carrier across the isolation barrier to represent a digital one and sends a no signal to represent the digital zero. The receiver demodulates the signal after advanced signal conditioning and produces the output. The symmetrical design of each isolation channel improves the CMTI performance and reduces the radiated emissions caused by the high-frequency carrier. The block diagram of an isolation channel integrated in the AMC1306 is shown in Figure 49.
