Product Summary

The TCM3105JE is a single-chip asynchronous frequency-shift-keying (FSK) voice-band modem that uses silicon-gate CMOS technology to implement a switched-capacitor architecture. The TCM3105JE is pin selectable (TXR1, TXR2, and TRS) for a wide range of transmit /receive baud rates and is compatible with the applicable BELL 202 or CCITT V23 standards. Operation is fully reversible, thereby allowing both forward and backward channels to be used simultaneously.

Parametrics

TCM3105JE absolute maximum ratings: (1)Supply voltage range, VDD: –0.3 V to 10 V; (2)Input voltage range, VI (any input): –0.3 V to VDD; (3)Operating free-air temperature range, TA: –10 to 70℃; (4)Storage temperature range: – 55 to 150℃; (5)Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 260℃; (6)Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 300℃.
