Functional Description
The CY2XP41 is a PLL (Phase Locked Loop) based high
performance clock generator. It is optimized to generate high
performance clock frequencies for DVD-R applications. It uses
Cypress’s low noise VCO technology to achieve less than 1 ps
typical RMS phase jitter, that meets application jitter
requirements. The CY2XP41 has a crystal oscillator interface
input and one LVPECL output pair.
