PCI/PXI-9820
2-CH 65 MS/s 14-Bit Digitizers with SDRAM
Introduction
ADLINK’s PCI/PXI-9820 is a 65 MS/s, high-resolution PXI digitizer with deep SODIMM SDRAM memory. The device
features flexible input configurations, including programmable input ranges and user-configurable input impedance. With
the deep onboard acquisition memory, the PCI-9820/PXI-9820 is not limited by the 132 MB/s bandwidth of PCI bus and
can record the waveform for a long period of time. The PCI-9820/PXI-9820 is ideal for high-speed waveform capturing,
such as radar and ultrasound applications, as well as software radio applications, or those signal digitizing applications
which need deep memory for data storage.
PCI-9820
■Analog Input
The PCI/PXI-9820 device features two analog input channels. The small signal bandwidth of each channel exceeds 30
MHz. The input ranges are programmable as either ±5 V or ±1 V. The 14-bit A/D resolution makes the PCI/PXI-9820
ideal both for time-domain and frequencydomain applications.
■Acquisition System
ADLINK PCI/PXI-9820 device uses a pair of 65 MS/s, 14-bit pipeline ADCs to digitize the input signals, and the device
PXI-9820
provides an internal 60 MHz timebase for data acquisition. The maximum real-time sampling rate is 60 MS/s with internal
timebase, and is up to 65 MS/s with external timebase. By using a "ping pong" mode, the sampling rate is up to 120
MS/s with internal timebase or 130 MS/s with external timebase.

SDRAM ranging from 128 MB to 512 MB.
The digitized data are stored in the onboard SDRAM before
being transferred to the host memory. The PCI/PXI-9820
device uses the scatter-gather bus-mastering DMA to move
data to the host memory. If the data throughput from the
PCI/PXI-9820 is less than the available PCI bus bandwidth,

■Triggering
The PCI/PXI-9820 device features flexible triggering functionalities, such as analog and digital triggering. The analog
trigger features programmable trigger thresholds on rising or falling edges on both input channels. The 5 V/TTL digital
trigger comes from PXI trigger bus or the external SMB connector for synchronizing multiple devices.
Post-trigger, pre-trigger, delay-trigger and middletrigger modes are available to acquire data around the trigger event.
The PCI/PXI-9820 also features repeated trigger acquisition, so you can acquire data in multiple segments coming with
successive trigger events at extremely short rearming interval.

■ Calibration
The auto-calibration function of the PCI/PXI-9820 is
performed with trim DACs to calibrate the offset and gain
needed by the board. Because all the calibration is conducted
automatically by software commands, users don't have to
adjust trimpots to calibrate the modules manually.
