IDT announces breakthrough technologies enabling industry’s lowest phase noise VCO and fractional output divider

USA: Integrated Device Technology Inc. (IDT) has announced two breakthrough technologies enabling the industry’s lowest phase noise voltage-controlled oscillator (VCO) and fractional output divider.

IDT’s latest technologies reinforce the company’s leadership in timing by empowering customers to solve phase noise-related challenges in high-performance communication and networking applications.

IDT’s new VCO technology will be leveraged into next-generation clock generator products, and has been demonstrated to achieve less than 50 femtoseconds (fs) 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 (ps) 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.
