CY2DP1504ZXCT

Overview

The CY2DP1504ZXCT is a 1:4 LVPECL fanout buffer with selectable clock input, manufactured by Infineon Technologies (formerly Cypress Semiconductor). It translates differential or single-ended inputs to four LVPECL output pairs. The device operates at frequencies up to 1.5 GHz with a maximum additive RMS phase jitter of 0.15 ps at 156.25 MHz. It supports 2.375 V to 3.465 V supply voltages and features synchronous clock enable for glitch-free transitions. Packaged in a 20-TSSOP, it ensures low skew and propagation delay for high-speed clock distribution.

Feature Summary

• Selectable input between two differential pairs (LVPECL, LVDS, HCSL, CML) via IN_SEL pin
• Translates single-ended CMOS inputs to 3.3 V LVPECL levels using resistor bias on INx#
• Maximum output-to-output skew of 30 ps and propagation delay of 480 ps
• Synchronous clock enable function prevents glitches during enable/disable periods

Applications

• High-speed clock distribution systems
• Data center power solutions
• Server power supply units (PSU)
• AI accelerator cards
• Telecommunications infrastructure DC-DC conversion

Procurement Notes

Verify the ordering suffix 'T' confirms Tape & Reel packaging. Confirm the commercial temperature range (0°C to 70°C) matches application requirements. Ensure the datasheet version Rev. *N is referenced for accurate electrical specifications. Check for RoHS compliance status as indicated in the ordering information.

Selection Notes

Select this component when low additive jitter (0.15 ps max) and low skew are critical. Use the ZXI variant for industrial temperature ranges (-40°C to 85°C). Ensure input signals meet the minimum differential amplitude of 400 mV for specified AC performance. Verify supply voltage compatibility with 2.5 V or 3.3 V systems.

Part Context

This part belongs to the CY2DP1504 family of ultra-low noise fanout buffers. It was originally developed by Cypress Semiconductor Corporation before acquisition by Infineon Technologies. The device is designed to replace older buffering solutions requiring precise timing alignment in multi-clock domain environments.
