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.
