■ Selectable output frequency: 62.5 MHz or 75 MHz
■ Low RMS phase jitter at 75 MHz, using 25 MHz crystal
(1.5 MHz–10 MHz): 0.27 ps (typical)
■ Low RMS phase jitter at 62.5 MHz, using 25 MHz crystal
(1.5 MHz–10 MHz): 0.38 ps (typical)

■ Supply voltage: 3.3 V
■ Commercial temperature range
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.
