Innovative Integration Announces the Atropos

Atropos is an XMC I/O module with precision, low-noise clock generation and distribution for data acquisition and communications timing applications. The module has four output clocks and four output triggers as well as a clock/reference input and a trigger input. Multiple Atropos cards can be cascaded to synthesize dozens of phase-synchronous, ultra-low-jitter clocks and triggers within RADAR, beam steering and MIMO applications.

Multiple Atropos cards can be cascaded to synthesize dozens of phase-synchronous, ultra-low-jitter clocks and triggers within RADAR, beam steering and MIMO applications.

In the sample clock generation mode, the Atropos can generate clocks from 74.06 to 3080 MHz. All clock outputs may be referenced to an on-card 280 ppb temperature-compensated oscillator, or an external clock input. In distribution mode, a supplied clock and trigger are buffered and distributed 1:4. The PLL circuit is fully programmable, providing excellent accuracy over a wide frequency range.

Example code is provided that supports control of all Atropos features. Software tools for host development include C++ libraries and drivers for Windows and Linux.
