7.3.3 Isolation Channel Signal Transmission
The AMC1336 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 43 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 common-mode transient immunity (CMTI) performance and reduces the radiated emissions caused by the high-frequency carrier. Figure 43 shows the block diagram of an isolation channel integrated in the AMC1336.
