CY2DL1504ZXIT

Overview

The CY2DL1504ZXIT is a high-performance fanout buffer and multiplexer from Infineon Technologies, designed for clock distribution applications. It features a 2:4 input-to-output ratio with differential inputs supporting CML, HCSL, LVDS, and LVPECL signals, and provides four differential LVDS outputs. The device operates at frequencies up to 1.5 GHz with a supply voltage range of 2.375V to 3.465V. It is housed in a 20-TSSOP package (0.173 inch width) and supports surface mount mounting. The component functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• Supports multiple differential input standards including CML, HCSL, LVDS, and LVPECL
• Provides four differential LVDS outputs for clock distribution
• Operates at maximum frequencies up to 1.5 GHz
• Integrated multiplexer functionality with 2:4 input/output ratio

Applications

• High-speed clock distribution networks
• Data communication systems requiring low-jitter buffering
• Server and storage backplane clocking
• Telecommunications infrastructure timing circuits

Procurement Notes

Verify the specific ordering suffix ZXIT confirms the Tape & Reel packaging format as indicated in the product parameters. Ensure the 20-TSSOP package dimensions match the design footprint requirements. Confirm that the 2.375V to 3.465V supply voltage range aligns with the target system power rails before procurement.

Selection Notes

Select this component when a single differential or single-ended source needs to drive four LVDS loads with minimal skew. The device accommodates various input logic levels (CML, LVPECL, etc.), simplifying interface design across different subsystems. Ensure the PCB layout supports the 20-TSSOP package thermal and electrical requirements for high-frequency operation up to 1.5 GHz.

Part Context

This part belongs to the category of clock buffers and drivers used for signal integrity management. It serves as a critical node in clock trees, converting diverse input formats into standardized LVDS outputs. Unlike PLL-based synthesizers, this device focuses on low-latency distribution and format conversion without frequency synthesis.

Replacement Considerations

Check for pin-compatible alternatives within the same Infineon family that offer similar 2:4 ratios and LVDS outputs. Verify that any substitute maintains support for the required input standards (CML, LVDS, etc.) and operates within the same 1.5 GHz frequency limit and voltage range.
