Description

The MX631 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.

individual logic outputs:

1. Tone Follower Output - A 'tone-following' logic

output producing a “Low” level for the period of a

correctdecodeanda“High”levelforabaddecode

or NOTONE.

2. Packet (Cumulative Tone) Mode Output - To

respond and/or de-respond after a cumulative

40ms of good tone (orNOTONE)inany48msperiod.

This process will ignore small fluctuations or fades

of a valid frequency input and is available for

µProcessor ‘Wake-Up’, Minimum Tone detection,

NOTONE indication or transient avoidance.

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, while the

12kHz and 16kHz frequency limits are accurately

defined by the use of an external 3.579545MHz

telephone-system Xtal or clock-pulse input.

The MX631, which demonstrates high 12kHz and

16kHz performance in the presence of both voice and

This system (12kHz/16kHz) selectable integrated

noise, can operate from either a single or differential circuit, which may be line-powered, is available in 16-pin

analog signal input from which it will produce two plastic DIP and SOIC surface mount packages.
