Semtech Simplifies the Design of Multiple Line Rate Cards with New Fractional Low Phase Noise Clock Synthesizer Platform
Industry’s best combination clock synthesizer of size, performance and frequency flexibility
Camarillo, California - July 31, 2013Semtech Corporation (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the general availability of the ACS1790T, a new low phase noise clock synthesizer.ToPSync® system synchronization solution, generating a low phase noise local reference clock that is aligned to the system timing recovered by the ACS9522T.
As a standalone frequency synthesizer, the ACS1790T offers outstanding flexibility with a 24-bit fractional feedback divider that generates any output frequency with a resolution of 0.5 parts-per-billion (ppb). This allows synthesis of any output frequency within the range of 10 MHz to 200 MHz on the LVPECL output and 2 KHz to 125 MHz on the LVCMOS output.
The part is packaged in a 4mm x 4mm 24-QFN package. All loop components are on-chip simplifying the circuit board layout and making the total solution footprint ideal for space-constrained applications. The combination of a high fractional resolution with a simple serial interface also makes the ACS1790T ideal for use in software-controlled loops where a translated but disciplined or traceable clock is required.
“The ACS1790T represents a key milestone in our mission to provide our customers complete timing solutions,” said David Spencer, Marketing Manager for the Semtech Timing Products. “It is our first really low phase noise product and is a great leap forward in performance, perfectly complementing our ToPSync product line and also serving as a versatile stand-alone frequency synthesizer with outstanding performance.”
