General Description
PCD3310A 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, wit 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.
PCD3310A 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.
` 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
