6.3.2 Isolation Channel Signal Transmission

The AMC3330-Q1 uses an on-off keying (OOK) modulation scheme to transmit the modulator output-bitstream across the capacitive SiO2-based isolation barrier. Figure 6-1 shows the block diagram of an isolation channel. The transmitter modulates the bitstream at TX IN with an internally generated, 480-MHz carrier and sends a burst 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 6-2 shows the concept of the on-off keying scheme.
