Description

The RFX144V24-S23 is a kind of MONOFAX facsimile modem which provides 14400 bps and 9600 bpas half-duplex capability with options supporting DigiTalk voice/ADPCM audio coding/decoding. These functions are supplied in a single VLSI device or two-device set (for speakerphone). The MDP (modem data pump) is packaged in a 100-pin PQFP. The MDP contains an internal integrated analog codec (IIA) and is pin-compatible with the RFX144V12/RFX96V12 and RFX144V12-S/RFX96V12-S MONOFAX modems. The XIA (external integrated analog codec), provided with speakerphone, is packaged in a 28-pin PLCC. The device enables cost-effective development of a common facsimile machine design with digital answering machine and/or full-duplex speakerphone.

There are some RFX144V24-S23 features as follows: (1)group 3 facsimile transmission/reception: HDLC framing at all speeds, receive dynamic range: 0 to -43 dBm; automatic adaptive equalization; fixed and programmable digital compromises equalization; (2)V.27 ter short train; (3)V.21 channel 2: DTMF detect and tone detect; (4)caller ID reception: compromise equalizer (-23 option); (5)DigiTalk voice codec (V24 option): 24 minutes of voice storage per 4 Mbit memory; near toll quality voice recording and playback; programmable AGC; error correction coding allows ARAM usage; DTMF detect, tone defect, and tone transmit; pitch synchronized fast slow playback; near-end echo cancellation; room monitor (V24-S option).

The following is about the RFX144V24-S23 absolute maximum ratings: (1)supply voltage, VDD: -0.5 to +7.0 V; (2)input voltage, VIN: -0.5 to +5VD+0.5 V; (3)input voltage, VIN: -0.5 to +5VA+0.5 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.
