CY2DL814ZXIT

Overview

The CY2DL814ZXIT is a 1:4 clock fanout buffer from the ComLink™ series, manufactured by Cypress Semiconductor Corp. It features a single configurable input supporting LVDS, LVPECL, or LVTTL signals and provides four differential LVDS output pairs. The device operates on a 3.135V to 3.465V supply voltage with a maximum frequency of 400 MHz. It offers low input capacitance, typical output-to-output skew of 85 ps, and propagation delay under 4 ns. Packaged in a 16-TSSOP (4.40mm width) in bulk, it supports industrial temperature ranges from -40°C to 85°C.

Feature Summary

• Configurable single input for LVDS, LVPECL, or LVTTL
• Four differential LVDS output pairs with selectable drive impedance
• Low skew (85 ps typ) and propagation delay (<4 ns typ)
• Operates at frequencies up to 400 MHz

Applications

• Data-communication clock management
• Level translation from single-ended to LVDS
• Distribution of LVDS-based clock signals

Procurement Notes

Verify the ordering suffix 'ZXIT' corresponds to the lead-free 16-pin TSSOP package in tape and reel format. Confirm the industrial temperature range (-40°C to 85°C) matches system requirements. Ensure the manufacturer is identified as Cypress Semiconductor Corp. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a 1:4 fanout with LVDS outputs is required. The input must be compatible with LVDS, LVPECL, or LVTTL levels. Ensure the load impedance matches the selectable 50-ohm or 100-ohm drive configuration. Verify that the 3.3V supply voltage and 400 MHz maximum frequency meet the design specifications.

Part Context

The CY2DL814 belongs to the ComLink™ series of network circuits produced using 0.35-micron CMOS technology. This series focuses on high-speed logic applications. The ZXIT variant specifically denotes the lead-free version in a 16-TSSOP package supplied in tape and reel form for automated assembly.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Review the datasheet for pin compatibility and electrical parameter overlaps before considering alternative devices.
