Brief Description

Subscriber Pulse Metering (SPM) detector to indicate

the presence, on a telephone line, of both 12kHz and

16kHz telephone call-charge frequencies.

input amplitude/sensitivities are component adjustable to

the user's national ‘Must/Must-Not Decode’

specifications via an on-chip input amplifier, whilst the

12kHz and 16kHz frequency limits are accurately

defined by the use of an external 3.579545MHz

telephone-system Xtal or clock-pulse input.

16kHz performance in the presence of both voice and

noise, can operate from either a single or differential

analogue signal input from which it will produce two

individual logic outputs.
