A 10 Bit Phase-Interpolator-Based Digital-to-Phase Converter for Accurate Time Synchronization in Ethernet Applications

Autor: Simon Buhr, Martin Kreissig, Christian Hoyer, Frank Ellinger

Publikováno v: ICECS

This work presents a 10 Bit digital-to-phase converter (DPC), for usage within an accurate time synchronization via Ethernet with a nominal frequency of 125 MHz. It is based on a 16-phase ring oscillator, stabilized by a phase-locked loop (PLL), foll

Low Power 16 Phase Ring Oscillator and PLL for Use in sub-ns Time Synchronization over Ethernet

Autor: Simon Buhr, Martin Kreissig, Frank Ellinger

Publikováno v: ICECS

A 16 Phase Ring Oscillator and phase locked loop (PLL) suitable for time synchronization with down to 500 ps accuracy via Fast Ethernet is presented. To reduce power consumption a new buffer stage known from CMOS level shifters is proposed. The power
