The DVD Specifications for Read-Only Discs Ver. 1.0, Aug. 1996 (hereafter referred to as the DVD Book) specify the jitter measurement method as follows: Time differences between all edges of an RF signal and a clock signal generated from the RF signal are measured to obtain their variation (a value) as jitter. The KJM6755A is a DVD jitter meter that employs the time interval method, a measurement method compliant with the DVD Book. Its specialized circuits for jitter measurement enable it to achieve significant cost reduction, as well as jitter measurement by inputting RF signals only in addition to conventional TIA-based two-signal (DATA to CLOCK) tests. Moreover, the PLL clock regeneration circuit, equalizer circuit, and slicer circuit are compliant with the DVD Book. Since its release, the KJM6755A has been acknowledged as the de facto standard for jitter measurement in DVD players thanks to its excellent cost-performance.
