Integrated Device Technology Inc. (IDT) has rolled out what it boasts a pair of breakthrough technologies that enable the industry's lowest phase noise voltage-controlled oscillator (VCO) and fractional output divider. The company said the solutions empower customers to solve phase noise-related challenges in high-performance communication and networking applications.

IDT's VCO technology will be leveraged into next-generation clock generator products, and has been demonstrated to achieve less than 50fs of RMS phase jitter over the wide-band 1kHz to 61.44MHz 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, said IDT. 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, noted the company.

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 0.7ps of integrated RMS phase jitter over the standard 12kHz to 20MHz 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.
