CY2XP24ZXI

Clock Generators, PLLs, Frequency Synthesizers Overview

The CY2XP24ZXI is a PLL-based crystal to LVPECL clock generator manufactured by Infineon Technologies (formerly Cypress Semiconductor). It operates on a 3.3 V or 2.5 V supply and utilizes an external 25 MHz parallel resonant crystal. The device generates selectable output frequencies of 156.25 MHz or 187.5 MHz via the F_SEL pin, corresponding to multipliers of 6.25x or 7.5x. It features low RMS phase jitter of 0.33 ps typical at 156.25 MHz (1.875–20 MHz offset) and provides one differential LVPECL output pair in an 8-pin TSSOP package.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Generates high-performance clock signals optimized for 10 Gb Ethernet, Fibre Channel, and SATA applications using low noise VCO technology.
• Provides a single differential LVPECL output pair with configurable frequency selection based on external logic input.
• Supports commercial and industrial temperature ranges within a compact Pb-free 8-pin thin shrunk small outline package.
