The TCM3105 from Texas Instruments is a single-chip asynchronous frequency-shift-keying (FSK) voice-band modem. It utilizes silicon-gate CMOS technology and a switched-capacitor architecture.
This IC is pin-selectable for a wide range of transmit and receive baud rates, compatible with Bell 202 and CCITT V23 standards. It supports transmit modulation at 75, 150, 600, and 1200 baud, and receive demodulation at 5, 75, 150, 600, and 1200 baud. The device offers half-duplex operation up to 1200 baud and full-duplex operation up to 1200 baud transmit and 150 baud receive.
Key features include on-chip group equalization and transmit/receive filtering, carrier-detect-level adjustment, and a carrier-fail output. It operates from a single 5-V power supply and boasts low power consumption. The TCM3105JE and TCM3105NE variants are characterized for operation from -40°C to 85°C, while the TCM3105DWL, TCM3105JL, and TCM3105NL variants operate from 0°C to 70°C.
Designed with reliable CMOS silicon-gate technology, the TCM3105 is suitable for applications requiring efficient FSK modulation and demodulation. Its integrated features simplify system design by reducing the need for external components.
