Patent number: 7102446Abstract: A phase lock loop (PLL) for controlling a sampling clock or other clock, and a data sampling circuit, transceiver, or other device including such a PLL. The PLL includes a multi-range VCO, at least one fine control loop for controlling the VCO, and a coarse control loop for controlling the VCO by changing its frequency-voltage characteristic. The coarse control loop includes a frequency lock detector and voltage range monitoring logic. Typically, the frequency lock detector locks operation of the coarse control loop when the difference between the VCO output clock frequency and a reference frequency decreases to within a predetermined threshold, and the unlocked coarse control loop employs the voltage range monitoring logic to change the VCO frequency-voltage characteristic when the VCO's fine control voltage leaves a predetermined range.Type: GrantFiled: February 11, 2005Date of Patent: September 5, 2006Assignee: Silicon Image, Inc.Inventors: Hyung-Rok Lee, Moon-Sang Hwang, Sang-Hyun Lee, Bong-Joon Lee, Deog-Kyoon Jeong
