Model 674DM Dual Stream PCM Bit Sync Mezzanine
The Model 674DM Advanced Digital PCM Bit Sync is a compact ‘mezzanine’ design that provides a high-performance yet cost-effective bit sync add-on to Acroamatics’ Model 1632AP Dual Stream PCIe multi-function PCM TM processing card product. The 674DM is compatible with both legacy and new telemetry standards. Based on our 3rd generation bit sync design, it shares the latest techniques in FIR filtering, digital phase-locked loop, NCO clock reconstruction, and digital amplitude and offset control with Acroamatics’ best-in-class dual-channel PCIe 1631AP and 2430D unit range bit syncs.
Dual Bit Sync Mezzanine
Companion to 1632AP PCIe Dual Decom
Multiple Program Controlled Inputs and Outputs
Compatible with legacy card components
Supports Self-Test and Link Validation features
Tunable Bit Rate Range: 8 bps to 40 Mbps, all codes
Best in Class Noise Performance within 0.50 db of theoretical
Incorporating a leading-edge FPGA, this modern design delivers a significantly reduced parts count, improved reliability, and expanded capabilities – including options normally found only in box-level and multi-card bit sync/ encoder designs. The 674DM supports options such as Frame Sync Pattern Verification, BERT, PRN, and programmable PCM simulator, and Convolutional encode/decode.
The Model 674DM PCM Bit Sync is fully compatible with legacy Acroamatics TDP system and remote Bit Sync utility software set-ups, easily meeting and exceeding all IRIG performance and functional requirements.
Additional Features
Fast sync acquisition within 50 bit transitions, typical
Best in Class Sync Retention to 1024 bits without transition
Data Quality and Signal Test:
- BERT / PRN BER Link Test Mode
- Frame Sync PCM BER Monitor
- Frame Lock/Loss Monitor
- Eb/No Signal Quality Output
- Viterbi Error Monitor / Stats
- Data Simulator/Generator
Processes all IRIG Codes Remote Software Operations
Both ADAT WIN & LINUX, standalone Windows GUI Setup, & Operation GUI’s supported
- Status of all Acro Bit Syncs in a system or network may be controlled by a single interface, with drop-down menus for individual cards. The software automatically recognizes all available bit syncs & their features.
- Instant set-up, store, and recall
