Title: Integrated circuit for changing relation in phase between at least one clock phase output and reference clock
Inventor: MERU BEEZESU
IPC: H03K5/05
Filed: 1991-03-01
Abstract: PURPOSE: To generate a clock phase with a frequency equal to or higher than the frequency of a reference clock from the reference clock without necessitating any PLL. CONSTITUTION: This integrated circuit is formed of an integrated circuit device which changes a phase relation between at least one clock phase output and a reference clock. A sequence controller 16 is connected with a waveform synthesizer 19 which generates at least one clock phase output. The clock phase output from the waveform synthesizer 19 is returned to a skew controller 18. A de-skew controller measures a skew between a falling edge part of the clock phase output and a rising edge part of the reference clock and supplies a control signal to a shifter. The shifter shifts an input pattern to a digital time area converter DTC so that the clock phase output can be automatically de-skewed in relation with the reference clock. A sampling window circuit in the de-skew controller is connected with the shifter.
