Qualcomm Announces A New Single-Chip Viterbi/Trellis Decoder Device

Qualcomm Incorporated (NASDAQ: QCOM) today announced a new combined Viterbi/Trellis Decoder integrated circuit. The Q1900 offers users the combined benefits of Qualcomm's highest speed Viterbi Decoder, the Q1650C-3N, and highest speed Trellis Decoder, the Q1875C-75N, on a single device.

The Q1900 supports data rates up to 25 Mbps in Viterbi Mode and 75 Mbps in Trellis Mode. The Viterbi Mode supports four k=7 convolutional code rates: 1/3, 1/2, 3/4 and 7/8. The Trellis Mode supports two k=7 convolutional code rates: 2/3 for 8 PSK and 3/4 for 16 PSK. Full duplex encode and decode is available in both Viterbi and Trellis Modes.

The Q1900 Viterbi Mode supports channel Bit Error Rate (BER) measurements and built-in phase synchronization for Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), and Offset Quadrature Phase Shift Keying (OQPSK) modulation techniques. The Trellis Mode supports built-in phase synchronization for 8-PSK and 16-PSK.

The Q1900 is available in a 84-pin PLCC (Q1900C-1N) or 100-pin VTQFP (Q1900C-1S3) package. The Q1900C-1N is pin-for-pin and backwards compatible with all Qualcomm Q0256 and Q1650 Viterbi decoders and Q1875 Trellis products. The Q1900C-1S3 is functionally compatible with the Q0256, Q1650 and Q1875 and its ultra low profile is an optimal solution for PCMCIA requirements.

The Q1900 is well suited for many commercial satellite communication networks including INMARSAT and INTELSAT. The low-cost and high performance of the Q1900 make it ideal for Forward Error Correction (FEC) requirements in systems such as 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.

Pricing for the Q1900 Viterbi/Trellis Decoder in 1000-piece quantities is $16 for the PLCC package and $18.00 for the VTQFP package. Samples are available now, with production quantities available in March of 1997.
