Noise XT Introduces SLC dual clock synthesizer
June 4, 2014. Noise eXtended Technologies (Noise XT) at the International Microwave Symposium introduced the 2-MHz to 7-GHz SLC ultra-low jitter/dual clock synthesizer. The SLC is a single- or dual-clock USB synthesizer with low jitter in a small package, offering a noise floor of -170 dBc/Hz at 10 MHz. The SLC measures 85 x 110 x 200 mm.
“The SLC is designed to provide excellent clock or LO (local oscillator) substitution signals to semiconductors where jitter and noise really matter. Typically, the SLC will be used to drive data converters (ADC and DAC), direct digital synthesizers (DDS), or high-speed FPGAs and serial links to achieve the highest performance,” said Guillaume de Giovanni, president, Noise XT.
The SLC serves R&D and production engineers working in the semiconductor industry where accurate timing matters. Wireless applications, particle colliders, digital semiconductor testing, and network time synchronization are a few of the applications. Products that will benefit most from using the SLC are digital transceivers used in software defined radio (SDR) applications and high-speed semiconductor testers. The SLC is used as either a local oscillator or as a clock in single or dual configurations allowing smaller footprint per channel.
In jitter measurements, the lower the jitter, the more accurate the time will be, enabling more bandwidth and better signal-to-noise (SNR) ratio. The result is fewer transmission errors and better detection of weak signals.
The SLC uses the latest component technology to maximize the cost/performance ratio on a 100 x 160 mm internal board. The combination of multi-DDS (digital direct synthesis) with a PLL is used to achieve the SLC’s ultra-low jitter performance.
“To our knowledge, no one else offers the multi-DDS plus PLL combination to achieve this level of jitter performance at such a low cost,” said Laurent Adrien, SLC lead designer.
The SLC offers up to 135 dB SNR for ADC/DAC testing, USB/SPI/Ethernet control, and a single or dual configuration in the same compact housing
The SLC Low-noise Compact Dual Synthesizer will be available in eight weeks upon receipt of order with first shipments in Q4. Pricing starts at €3,950.
