1 / 7 page  FULL-DUPLEX SCRAMBLER FOR CORDLESS TELEPHONES Figure 1 - Simplified Signal Paths 3) A 3.3 kHz inversion carrier (injection tone). 4) A 14 th order bandpass filter (300-3000 Hz). 5) Input op-amps with externally adjustable gain. The MX118 uses CMOS switched-capacitor filter technology and operates from a single supply in the range of 3.0 V to 5.5 V. The inversion carrier's frequency and filter switching clock are generated on-chip using an external 4.433619 MHz crystal or clock input.
