  • Page 75: External Clock

    Copyright © 2025 Alazar Technologies Inc. External Clock The ATS9628 PCI Express Digitizer allows you to bypass the on-board clock oscillator and supply your ADC clock. This feature is extremely important in many RF applications in which phase measurements must be made between the inputs themselves or between the inputs and an external event.
  • Page 76 10 MHz Reference Clock ATS9628 allows the user to synchronize the sampling clock to an external 10 MHz reference signal. This is useful in many RF applications. Reference clock frequency must be 10 MHz ± 0.1 MHz and should have a high slew rate.

  • Page 83: Streaming Data Across The Bus

    Copyright © 2025 Alazar Technologies Inc. Streaming Data Across the Bus One of the most unique features of the ATS9628 is its on-board, dual-port acquisition memory, with custom Direct Memory Access (DMA), that can be used for signal storage. Data is acquired into the on-board memory before being transferred to the host PCT memory.
  • Page 84 This requires a software handshake which is heavily dependent on the operating system response time. ATS9628 solves this problem by providing on-board memory that can act as a very deep FIFO and an advanced custom DMA engine that can stream data to PC host memory at up to 1.6 GB/s (exact rate is motherboard dependent).
  • Page 85 Software still has to get involved in re-arming the hardware after every capture and again for reading the data from on-board acquisition memory. ATS9628’s proprietary AutoDMA circuitry allows the acquisition system to be re- armed by a hardware command and data transfer to be initiated by the hardware itself, thus removing virtually all “in-process”...
  • Page 86 ATS9628 features a high-performance memory management firmware that allows much faster data throughput in Traditional mode than previous generation digitizers. Traditional AutoDMA is the fastest way to move data into user buffers. It is the recommended method for new designs such as the ATS9628. ATS9628 User Manual...

  • Page 88 Continuous AutoDMA is also known as the data streaming mode. In this mode, data starts streaming across the PCI bus as soon as the ATS9628 is armed for acquisition. It is important to note that triggering is disabled in this mode.
  • Page 89 Triggered Streaming AutoDMA can easily acquire data to PC host memory at the maximum sustained transfer rate of the motherboard without causing an overflow.
