VA10V

The VA10V is a 1024 state error control decoder using the maximum likelihood Viterbi algorithm. The decoder is designed to decode 3GPP2 Reverse Traffic Channel encoded data as well as other custom coding solutions.

Features

• 1024 state (constraint length 11) 3GPP2 compatible Viterbi decoder
• Up to 258 MHz internal clock
• Up to 14.4 Mbit/s
• Rate 2/3, 1/2, 1/3 or 1/4
• Optional or standard code polynomials
• 8–bit signed magnitude or two's complement input data
• Optional continuous, terminated (1 to 246 data bits) or tail-biting (32 to 256 data bits) decoding
• Estimated channel bit error outputs
• Optional serial (continuous only) or parallel data input
• Optional automatic synchronisation for rate 1/2 QPSK and rate 1/2 to 1/4 BPSK
