General Information
Specifications
Model 5694 High-Speed Clock Generator
provides fixed-frequency sample clocks to
AMC Cobalt and Onyx boards in multiboard
systems. It enables synchronous sampling,
playback and timing for a wide range of
multichannel high-speed data acquisition
and software radio applications.

Sample Clock Synthesizer
The Model 5694 uses a high-precision,
fixed-frequency, PLO (Phase-Locked Oscillator) to generate an output sample clock.
The PLO accepts a 10 MHz reference clock
through a front-panel SMA connector. The
PLO locks the output sample clock to the
incoming reference. A power splitter then
receives the sample clock and distributes it
to four front panel SMA connectors.
The 5694 is available with sample clock
frequencies from 1.4 to 2.0 GHz.
On-board Reference Clock
In addition to accepting a reference clock
on the front panel, the 5694 includes an
on-board 10 MHz reference clock. The
reference is an OCXO (Oven-Controlled
Crystal Oscillator), which provides an
exceptionally precise frequency standard
with excellent phase noise characteristics.
Features
Physical Characteristics
■
The 5694 is a standard AMC board. The
board does not require programming and
the PCIe interface connector is used solely
for power. The board can be optionally
configured with a PCIe-style 6-pin power
connector allowing it to be used in virtually
any chassis or enclosure.
