Description

The FX621 is a single-chip, low-power CMOS tone detector designed for use in both PABX and general payphone applications for Subscriber Private Metering.

The Decode and Not-Decode band edges of FX621 are accurately defined by the use of an external 4.433619MHz crystal.

Operation to either of the 12kHz or 16kHz SPM systems is pin programmable, with system amplitude sensitivities and pulse-length timing being provided by the use of external components.
