Pulse and DTMF diallers with redial

Product specification

PCD3310; PCD3310A

1 FEATURES

• Pulse, DTMF and ‘mixed mode’ dialling

• Mixed mode dialling: start with pulse dial, end with

DTMF dial (e.g. for control of DTMF user equipment via

a pulse network)

• 23-digit memory stores last number dialled, or number

noted during conversation (notepad)

• Redial of both PABX and external calls

• Supports 16 dial keys: 0 to 9, ∗, # A, B, C, and D

• Supports 4 function keys:

– Program (P) used to input notepad numbers

– Flash (FL) allows re-dialling without on-hook

– Redial (R) recalls and redialls stored number

– Change from pulse dial to DTMF dial in

mixed mode (>)

• DTMF timing:

– for manual dialling, maximum duration burst/pause

intervals are user-determined, but at least minimum

duration burst/pause intervals are ensured

– for redial, minimum duration burst/pause intervals are

used

• On-chip voltage reference for supply and temperature

independent tone output

• On-chip filtering for low output distortion

(CEPT compatible)

• On-chip oscillator uses low-cost 3.58 MHz (TV colour

burst) crystal or piezo resonator

• Uses standard single-contact or double-contact

(common left open) keyboard

• Keyboard entries fully debounced

• Flash (register recall) output.

2 GENERAL DESCRIPTION

The PCD3310 and PCD3310A are single-chip silicon gate

CMOS integrated circuits. They are dual-standard diallers

for pulse or dual tone multi-frequency (DTMF) dialling, with

on-chip oscillators suitable for use with 3.58 MHz crystals.

Input data is derived from any standard matrix keyboard

for dialling in either the pulse or DTMF mode.

Numbers up to 23 digits can be retained in RAM for

dialling/redialling.
