Publication number: 20080063129Abstract: A system and method for transmitting and receiving through a high speed serial link with power up and power down capability. The exemplary embodiments of this invention involves a method of power up and power down the high-speed serial link without using high voltage swing control and signaling. Both the transmitter and the receiver wake up only during pre-defined burst cycles. During each burst cycle, data will be transmitted and received in burst mode. Outside each burst cycle, the transmitter and receiver will be powered off or partially powered off. Various phase-locked loop based circuit ensure the transmitter and the receiver can be locked in frequency and phase quickly at the time of power-up. The duration of the burst cycle and the interval between two adjacent burst cycles can be either fixed or changed by upper level protocol.Type: ApplicationFiled: September 11, 2006Publication date: March 13, 2008Inventor: Martti Voutilainen

Patent number: 7224737Abstract: To significantly reduce mobile station static power consumption, and to make it possible to use a high speed asynchronous link in the mobile station, the invention uses one of the amplitude levels of, preferably, a PAM-5 (Pulse Amplitude Modulation with five amplitude levels) modulation technique as a strobe signal to generate a change in the transmitted signal. The change in the transmitted signal makes it possible for a PAM-5 receiving circuit to sample and decode two consecutive occurrences of the same data bits. The use of this invention avoids the requirement to include an oscillator in the PAM-5 receiver, or to dedicate a signal line to transmit a clock signal from the transmitter to the receiver.Type: GrantFiled: October 10, 2003Date of Patent: May 29, 2007Assignee: Nokia CorporationInventor: Martti Voutilainen
