CY2XP31ZXC

Product Overview

The CY2XP31ZXC from Cypress Semiconductor Corp is a surface-mount clock generator integrated circuit intended for timing distribution and frequency synthesis tasks. The device uses a crystal input and provides an LVPECL output, with a maximum specified frequency of 312.5 MHz. It uses an 8-TSSOP package with a 4.40 mm width and operates from a 2.375 V to 3.465 V supply. The part includes one circuit and supports divider and multiplier functions, making it suitable for clocking subsystems that require a single differential output stage and a surface-mount footprint.

Key Features

• Clock generator integrated circuit with one circuit block.
• Includes PLL functionality.
• Crystal input and LVPECL differential output.
• Maximum frequency of 312.5 MHz.
• Input-to-output ratio of 1:1.
• Supports divider and multiplier functions.
• Operates from 2.375 V to 3.465 V supply.
• Specified operating temperature range of 0°C to 70°C.
• Surface-mount 8-TSSOP package, 4.40 mm width.

Applications

• Timing distribution boards where a crystal-referenced clock must be generated and delivered over an LVPECL interface.
• PLL-based clock generation in embedded or communications equipment that requires a surface-mount output stage.
• Test and measurement hardware that needs a single differential clock output for downstream logic.
• Backplane or module interconnect clocking where the 312.5 MHz maximum frequency and 1:1 ratio match the timing plan.

Design & Procurement Notes

When selecting the CY2XP31ZXC for a design, confirm that the crystal input, LVPECL output, 1:1 ratio, and 312.5 MHz maximum frequency align with the required timing architecture. The 2.375 V to 3.465 V supply range and 0°C to 70°C operating temperature range should be checked against the board power rails and ambient conditions. The 8-TSSOP surface-mount package and 4.40 mm width should be evaluated against available board area and mounting requirements, while the single-circuit configuration should be considered in clock tree planning.
