CY2XP31ZXI

Product Overview

The Cypress Semiconductor Corp CY2XP31ZXI is an 8-TSSOP clock generator IC that accepts a crystal input and provides an LVPECL output. It includes a PLL and supports a maximum frequency of 312.5 MHz with a 1:1 input-to-output ratio. The device operates from a 2.375 V to 3.465 V supply over a -40°C to 85°C temperature range and uses a surface-mount 8-TSSOP (0.173", 4.40mm Width) package.

Key Features

• Integrated PLL clock generator
• Crystal input and LVPECL output
• Maximum frequency 312.5 MHz
• 1:1 input-to-output ratio
• Divider and multiplier capability
• Single circuit implementation
• 2.375 V to 3.465 V supply voltage range
• -40°C to 85°C operating temperature range
• 8-TSSOP surface-mount package (0.173", 4.40mm Width)

Applications

• Generating a differential LVPECL clock signal from a crystal input in digital timing circuits
• Providing a single clock output with a 1:1 input-to-output ratio in board-level clock generation designs
• Supplying timing signals up to 312.5 MHz in circuits that require an 8-TSSOP surface-mount clock generator

Design & Procurement Notes

Design considerations include using a crystal input and LVPECL output consistent with the specified 1:1 input-to-output ratio and 312.5 MHz maximum frequency, and ensuring the supply remains within 2.375 V to 3.465 V across the -40°C to 85°C operating range. The 8-TSSOP surface-mount package supports compact board placement. Procurement should verify the exact CY2XP31ZXI part number because package dimensions, supply range, and output format are fixed by the device specification. The maximum frequency, supply range, and package form factor should be checked against the board's timing and layout constraints.
