Multi-Channel Demodulation
The AC digital programming capability of the XR-215A allows a single circuit be time-shared or multiplexed between two
information channels, and thereby selectively demodulate two separate carrier frequencies. Figure 19 shows a
practical circuit configuration for time-multiplexing the XR-215A between two FM channels, at 1MHz and 1.1MHz
respectively. The channel-select logic signal is applied to pin 10, as shown in Figure 19with both input channels
simultaneously present at the PLL input (pin 4). Figure 20shows the demodulated output as a function of the
channel-select pulse where the two inputs have sinusoidal and triangular FM modulation respectively.
