Features:
- Single-Slot 32 Bit PCI Express Module
- IRIG A, B, NASA 36, 1 PPS Sync Inputs
- HaveQuick Sync Input Option
The JXI2 PCI-Express Module provides
precision time with zero latency to the host computer over the
PCI bus. An on-board microprocessor automatically synchronizes the clock to reference signal inputs. The reference
signal inputs can be 1 PPS, IRIG or NASA time codes and
OEM optionally, GPS or HaveQuick. The clock can free run and be
set by commands from the host over the PCI Express bus.
The on-board clock accepts an IRIG A, B, or NASA 36 input
and accepts user input reference input signal delay information. An IRIG B code generator is OEM manufactured.
The advanced microprocessor on the PCI-Express module
constantly measures the time error between the on-board
clock and the reference input code and adjusts the error
measurement for propagation delay. In units with a disciplined TCXO or OCXO the residual error is used in an adaptive gain loop to adjust the frequency of the oscillator for
minimum error. If the incoming time code is missing, or corrupted by noise, the on-board clock is updated using the disciplined oscillator. When the input code is again useable the
correction loop is smoothly closed.
58 bits of BCD time data are available to the host computer
using two zero latency time reads. The time message contains units of microseconds through units of years. A status
word is available using an additional read.
The exact time-of-occurrence of random external events may
be captured by using the Event Time input. When the event
input is sensed the current time is saved in a buffer for later
interrogation by the host. The resolution of the time tag is
100 nanoseconds.
Internal or external processes may be automatically initiated
or terminated by using the Match Time feature. This feature
asserts an output when the clock's time matches that of the
user input start time. The output is terminated under user
control or when the pre-programmed stop time is encountered. The resolution of the Match Time comparison is one
microsecond.
Three user programmable pulse rates are provided. Two
pulse rates, Clock Low and Clock High, are available on the
multi-pin connector. The third rate generator provides heartbeat timing to the host. The divider for each of the three rate
generators is programmable by the host over the range 2-
65,535. The inputs to the rate generators are 3 MHz or 100
Hz for the heartbeat, 3 MHz for Clock High and 100 Hz for
Clock Low.
The GPS synchronization option adds worldwide time transfer
capability that can be traced to the U.S. Government standard
UTC-USNO. Very precise synchronization, automatic leap
year and leap second correction, and accurate position information are additional benefits provided by the OEM GPS option.
The JXI2 PCI-Express Module may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
Functions
The JXI2 PCI-Express module, when configured with the BIN37 option, provides a PCI-Express interface for communication with a host computer. It enables the processing of digital signal data. The module supports data acquisition, processing, and transmission in various communication systems. The hardware platform includes a PCI-Express slot in a host computer.
Platforms
Operates within a host computer via a standard PCI-Express slot. Interfaces with the host OS (Windows/Linux) through a software driver and API for time synchronization and event time-stamping. Connects externally via BNC connectors to receive time sources, such as IRIG-B or 1PPS, and outputs synchronized signals including 1PPS and programmable frequencies. Used in data acquisition, NTP/PTP time servers, and test range instrumentation requiring precise system-level timing.
Applications
The PCI-Express module with Option BIN37 is designed for network timing and synchronization, facilitates precise time transfer and frequency distribution across various network architectures. It operates on a PCI-Express interface, allowing for integration into servers and embedded systems. Common uses include precise time stamping, synchronization of financial transactions, and integration in communication infrastructure.
