IDT Enables Industry’s Lowest Phase Noise VCO And Fractional Output Divider

IDT���s new VCO technology will be leveraged into next-generation clock generator products, and has been demonstrated to achieve less than 50 femtoseconds of RMS phase jitter over the wide-band 1 kHz to 61.44 MHz integration range. The extremely low phase noise enables customers to generate the highest-quality reference clocks for use in wireless base-stations, wired networking, and other high-performance communications equipment. High-quality reference clocks improve communication signal quality on transmission and enhance signal recovery on reception, improving data throughput via lowered error rates. Customers can also reduce total system costs by simplifying filters due to reduced noise in the signal path.

In addition, IDT has developed an innovative fractional output divider circuit capable of generating any output frequency independent of the PLL’s operating frequency with less than 0.7 picoseconds of integrated RMS phase jitter over the standard 12 kHz to 20 MHz integration range. The ultra-low phase noise fractional output divider enables customers to generate multiple independent frequencies from a single PLL for use in noise-sensitive communications applications.

“As the worldwide leader in timing solutions, we’re excited announce these latest advancements is low-noise clocking technology,” said Christian Kermarrec, vice president and general manager of the Timing and Synchronization Division at IDT. “IDT has the innovative technology to solve the most difficult phase noise-related problems facing our customers today, such as in radio card data converter clocks, and optical transport network line-side reference clocks. A sub-50 fs phase jitter VCO and sub-ps phase jitter divider empower our customers to develop higher-performance systems with fewer resources devoted to error correction. We look forward to bringing these products to market over the upcoming months.”
