Description
The CMX661D4 is an IC chip used as a Dual Subscriber Pulse Metering (SPM) Detector on a telephone line to detect 12kHz or 16kHz telephone call charge frequencies. The detector's sensitivity can be set independently for each individual channel and outputs can be set to a high impedance state for device multiplexing requirements in PBX and PABX line card applications. This device operates on low power ranging from 3.0V to 5.0V.
