Applications
The circuit shown in Figure 6 illustrates the use of the MT88E41 device in a typical FSK receiver system. Bellcore
Special Report SR-TSV-002476 specifies that the FSK receiver should be able to receive FSK signal levels as
follows:
Received Signal Level at 1200Hz:
-32dBm to -12dBm
Received Signal Level at 2200Hz:
-36dBm to -12dBm
This condition can be attained by choosing suitable values of R1 and R2. The MT88E41 configured in a unity gain
mode as shown in Fig. 6 meets the above level requirements.
For applications requiring detection of lower FSK signal level, the input op amp may be configured to provide
adequate gain.
