Q1900C-1N Description

Short technical summary and product information.

The Qualcomm Q1900C-1N is a versatile Viterbi and trellis decoder chip, suitable for various commercial satellite communication networks like INMARSAT and INTELSAT. Its low cost and high performance make it ideal for Forward Error Correction (FEC) requirements in systems such as direct broadcast satellites (DBS), microwave point-to-point data links, and digital video transmission systems.

This decoder supports Viterbi mode rates of 1/3, 1/2, 3/4, and 7/8, and trellis mode rates of 2/3 and 3/4. It offers full duplex encoding and decoding capabilities in both modes. The Q1900C-1N can achieve data rates up to 30Mbps in Viterbi mode and up to 90Mbps (16-PSK) in trellis mode. It features automatic phase synchronization for BPSK, QPSK, 8-PSK, and 16-PSK modulation schemes.

Designed for ease of implementation, the Q1900C-1N includes an on-chip channel bit error rate (BER) monitor for Viterbi mode and a processor interface for simplified control and status monitoring. It operates with a voltage range of -0.3V to +7V and has a junction temperature rating of +150°C. The device is available in a standard 84-pin PLCC package, with a low-power CMOS implementation.

Applications for the Q1900C-1N include direct broadcast satellites (DBS), microwave point-to-point data links, very small aperture terminals (VSAT), digital modems, digital video transmission systems, high-speed data modems, and military and NASA communication systems.
