The AF121 and AF122 are 6th order elliptic bandpass filters designed for use with digital DTMF detectors. These filters are patible with tone detector circuits such as the Rockwell CRC8030 and the Mostek MK5102 DTMF digital receivers. The filters provide 40 dB separation between the high and low frequency signaling groups and the dial tone frequencies.
