The CMX631A is a low-power, system-selectable Subscriber Pulse Metering (SPM) detector that indicates the presence of both 12kHz or 16kHz telephone call-charge frequencies on a telephone line. Deriving its input directly from the telephone line, input amplitude/sensitivities are component adjustable to the user's national `Must/Must-Not Decode' specifications via an on-chip input amplifier. The 12kHz and 16kHz frequency limits are accurately defined by the use of an external 3.579545MHz telephone-system Xtal or clock-pulse input. |
