Brief Description

The FX631 is a low-power, system-selectable

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

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

correct decode and a “High” level for a bad

decode or N^OTONE.

Subscriber Pulse Metering (SPM) detector to indicate

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

16kHz telephone call-charge frequencies.

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, 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.

The FX631, which demonstrates high 12kHz and

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.

2. Packet (Cumulative Tone) Mode Output - To

respond and de-respond after a cumulative 40ms

of good tone (or NOTONE) in any 48ms period.

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.

This system (12kHz/16kHz) selectable microcircuit,

which may be line-powered, is available in 16-pin plastic

DIL and surface mount SOIC and 24-pin plastic SSOP

packages.
