Transceiver Macro with Spread-Spectrum Clocking Capability for AC-Coupled Cable Interfaces

Autor: Takefumi Yoshikawa, Tsuyoshi Ebuchi, Takashi Hirata, Yoshihide Komatsu

Publikováno v: IEICE Transactions on Electronics. :1444-1452

A transceiver macro for high-speed data transmission via cable in vehicles is proposed. The transceiver uses ac coupling and bidirectional interface topology for protecting LSIs against unexpected short of cable and harness/chassis and has a spread-s

An ultra-wide range Bi-directional transceiver with adaptive power control using background replica VCO gain calibration

Autor: Tomoko Chiba, Masatomo Miura, Shiro Dosho, Yoshihide Komatsu, Takefumi Yoshikawa, Tsuyoshi Ebuchi, Toru Iwata

Publikováno v: 2010 Symposium on VLSI Circuits.

A transceiver with adaptive power control using a process and frequency monitor (PFM) is proposed. The PFM employs gain calibration with a replica voltage-controlled oscillator (VCO) and operates in the background. A five-bit digital code detected by

Bi-directional AC coupled interface with adaptive spread spectrum clock generator

Autor: Takashi Hirata, Tsuyoshi Ebuchi, Yoshihide Komatsu, Takefumi Yoshikawa

Publikováno v: 2007 IEEE Asian Solid-State Circuits Conference.

We propose a method of reducing a quantization noise and a spectrum peak utilizing an adaptive spread spectrum clocking PLL (SSC-PLL) circuit for bi-directional and AC coupled interface. To realize a high speed, wide range, bi-directional and long ca
