14GHz Integer-N High-Speed PLL

Overview

1-VIA’s broad portfolio of general-purpose and optimized LC-PLLs offer a wide range of clocking solutions.

The Integer-N high-speed PLL creates quadrature clocks with good duty cycle and excellent jitter characteristics for high-speed, source-synchronous interfaces and other high-speed logic applications.

The PLL is implemented using 1-VIA’s proprietary architecture, utilizing an integrated Low-Dropout (LDO) regulator and bandgap reference generator. This architecture helps achieve exceptional jitter performance whilst also reducing power consumption.

Key Features

Type II hybrid Integer-N LC-PLL
Quadrature clocks at 14GHz and 7GHz
Fast locking
Low-power and ultra-low-jitter (<50fs-rms)
Analog and digital lock-detector for calibration and DSP purposes
Auto-calibration at start-up and “in background” for PVT drift

Benefits

Wide functional range allows all frequencies in a system to be synthesized with one PLL macro
Low area on chip -- keepouts = DRC limit in most cases
No external components required
No additional supply decoupling required
Self biased and automatically adjusts for any input frequency, so no complicated programming is required
