Description

The RFX144V12-S is a kind of MONOFAX facsimile modem. It features Rockwell's DigiTalk speech processing technology for voice compression and full-duplex speakphone capability. The DigiTalk voice coder/decoder compresses voice at 5.7 kbps with near toll quality playback, allowing up to 12 minutes of speech to be stored in 4 Mbits of memory. The DigiTalk speakerphone provides full-duplex hands-free voice conversion with both acoustic and line echo cancellation. These functions are supplied in a two-device set: a modem data pump (MDP) packaged in a 100-pin PQFP and a secondary integrated analog codec (SIA) device packaged in a 28-pin PLCC.

There are some RFX144V12-S features as follows: (1)V.27 ter short train; (2)caller ID reception; (3)concurrent DTMF, FSK and tone reception; (4)programmable transmit level; (5)software compatible with other MONOFAX modems; (6)programmable dual tone detection; (7)programmable tone detection; (8)programmable interface memory interrupt; (9)programmable ring detector; (10)8-bit or 16-bit high quality audio mode transmission/reception; (11)DTE interface: two alternate ports: selectabel microprocessor bus (6500 or 8085) and CCITT V.24 (EIA/TIA-232-E compatible) interface; (12)TTL and CMOS compatible; (13)+5 V operation; (14)power consumption: normal: 620 mW (typ) and sleep: 10.8 mW (typ).

The following is about the RFX144V12-S absolute maximum ratings: (1)supply voltage, VCC: -0.5 to +7.0 V; (2)input voltage, VIN: -0.5 to +5VD+0.5 V; (3)input voltage, VIN: -0.3 to +5VA+0.3 V; (4)voltages applied to outputs in high impedance (off) state, VHZ: -0.5 to +5VD+0.5 V; (5)DC input clamp current, IIK: ±20 mA; (6)DC output clamp current, IOK: ±20 mA; (7)static discharge voltage (25), VESD: ±2500 V; (8)latch-up current (25), ITRIG: ±200 mA; (9)operating temperature range, TA: 0 to 70 commercial and -40 to +85 extended; (10)storage temperature range, TSTG: -55 to +125.
