Overview:
The DBS-120S combines the functions of Bit Synchronization and Data Decommutation into a single low cost PCMCIA type II card. The card can be installed in a portable PC compatible platform for preflight or lab test. The Bit Synchronizer provides full featured clock reconstruction, data recovery and code conversion. The Bit Sync accepts PCM inputs at rates of up to 20 Mbps for NRZ codes and up to 10 Mbps for BiØ codes with amplitudes from 0.1 to 5.0 Volts p-p. The Bit Sync input impedence is programmable to 50 ohms, 75 ohms or 10k ohms. TTL and RS-422 compatible PCM data and 0°/180° clock Bit Sync outputs are provided. The Bit Sync output is also internally connected to the on card Decom. A Bit Error Rate (BER) measurement capability with an on card Test Data Simulator is included to allow characterization of data link quality. The Data Decommutator provides full IRIG Frame Synchronization and data Decommutation. The Decom accepts PCM data at rates up to 20 Mbps from the on card Bit Sync or an external source. The Decom external data and clock input is programmable for RS-422, 10KohmsTTL, or 75 ohms TTL. Decommutated data words, and frame time tag are made available via the PCMCIA bus for analysis, archival, and monitoring. The card also features a Playback Mode. In this mode the card regenerates archived PCM Data at programmable rates up to 20 Mbps.
