Patent number: 8650421Abstract: The present invention discloses a network interface apparatus comprising two power regulators, one of which is a system power regulator for supplying a first supply voltage to a physical layer and a medium access control layer in the network interface apparatus, and the other one is an uninterrupted power regulator for supplying a second supply voltage to a power management module. When the network interface apparatus operates in a disconnection status, the system power regulator is disabled so as not to supply the first supply voltage, and the uninterrupted power regulator still provides the second supply voltage to the power management module.Type: GrantFiled: February 10, 2010Date of Patent: February 11, 2014Assignee: Realtek Semiconductor Corp.Inventors: Ting-Fa Yu, Li-Wei Fang, Tsung-Cheng Lee, Chien-Sheng Lee

Patent number: 8554260Abstract: A communication system includes a first network device and a second network device. A power consumption control method applied to the communication system includes the steps of: checking a receiving capability of the first network device to generate a first checking result; and selectively notifying the second network device to adjust a transmitting capability of the second network device according to the first checking result. When the first checking result indicates that the receiving capability of the first network device is greater than a first threshold, transmit a first notice signal to notify the second network device. When receiving the first notice signal, lower the transmitting capability of the second network device.Type: GrantFiled: March 18, 2010Date of Patent: October 8, 2013Assignee: Realtek Semiconductor Corp.Inventors: Liang-Wei Huang, Ta-Chin Tseng, Ting-Fa Yu, Li-Wei Fang

Patent number: 8406336Abstract: A communication device and receiving method thereof are disclosed in embodiments of the present invention. The communication device includes an extra digital to analog converter, an inverse partial response filtering circuit and an analog to digital converter. The extra digital to analog converter receives a first digital signal and generates a pulse shaped analog signal. The inverse partial response filtering circuit receives a first difference signal, and adjusts a response of the inverse partial response filtering circuit to generate an adjusted signal, wherein the first difference signal equals the result of subtracting the pulse shaped analog signal from a receiving signal. The analog to digital converter converts the adjusted signal to generate a second digital signal.Type: GrantFiled: September 10, 2010Date of Patent: March 26, 2013Assignee: Realtek Semiconductor Corp.Inventors: Liang-wei Huang, Ting-Fa Yu, Ta-Chin Tseng, Li-Wei Fang

Patent number: 8253500Abstract: A frequency-phase adjusting device includes a first controller, a second controller, and an oscillating circuit. The first controller generates a first control signal according to a target frequency and a current frequency. The second controller generates a second control signal according to the first control signal, wherein the second control signal is related to a first frequency difference, a second frequency difference, and a designated duration. The oscillating circuit adjusts the current frequency according to the first frequency difference, the second frequency difference, and the designated duration. The current frequency is set as a first frequency during a first duration, set as a second frequency during the designated duration, and set as a third frequency during a second duration. The first frequency difference equals a difference between the first frequency and the second frequency, and the second frequency difference equals a difference between the second frequency and the third frequency.Type: GrantFiled: July 21, 2010Date of Patent: August 28, 2012Assignee: Realtek Semiconductor Corp.Inventors: Liang-Wei Huang, Ting-Fa Yu, Ta-Chin Tseng, Li-Wei Fang
