Crystal to LVPECL Clock Generator
• One LVPECL Output Pair
• Selectable output frequency MHz or MHz
• External crystal frequency 25 MHz
• Low root mean square RMS phase jitter at MHz, using
25 MHz crystal MHz to 20 MHz ps typical
• Pb-free 8-Pin thin shrunk small outline package TSSOP

Package
• Supply voltage V or V
• Commercial and industrial temperature ranges

Functional Description

The CY2XP24 is a PLL phase locked loop based high performance clock generator. It is optimized to generate 10 Gb Ethernet, Fibre Channel, and other high performance clock frequencies. It produces an output frequency that is either times or times the crystal frequency. It uses Cypress’s low noise VCO technology to achieve low phase jitter, that meets both 10 Gb Ethernet, Fibre Channel, and SATA jitter requirements. The CY2XP24 has a crystal oscillator interface input and one LVPECL output pair.
