CY2DP818ZI-2

Overview

The CY2DP818ZI-2 is a single-circuit clock fanout buffer manufactured by Cypress Semiconductor Corp. It provides an 1:8 distribution ratio with differential input and output capabilities. The device supports LVDS, LVPECL, and LVTTL inputs while delivering LVPECL outputs. It operates at a maximum frequency of 350 MHz with a supply voltage range of 3.135V to 3.465V. Designed for surface mount installation, it is housed in a 38-TSSOP package (0.173" width) and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

• 1:8 Clock Fanout Buffer with differential input/output
• Supports LVDS, LVPECL, and LVTTL input signals
• Maximum operating frequency of 350 MHz
• Housed in a 38-TSSOP surface-mount package

Applications

• High-speed clock distribution networks
• Differential signal buffering in data communication systems
• Clock tree generation for high-frequency digital circuits

Procurement Notes

Verify the specific ordering suffix 'ZI-2' against official Cypress documentation to confirm pinout, packaging, and electrical characteristics match the 38-TSSOP specification. Ensure compatibility with LVPECL output requirements and the specified 3.135V–3.465V supply voltage range during component sourcing.

Selection Notes

Select this component when an 1:8 fanout ratio with differential signaling is required. Confirm that the system design accommodates LVPECL outputs and supports the necessary input formats (LVDS/LVPECL/LVTTL). Verify that the 350 MHz frequency limit meets the application's timing requirements and that the 38-pin TSSOP footprint fits the PCB layout constraints.

Part Context

This part belongs to the Cypress clock buffer family, designed for precise clock distribution. It serves as a critical interface between source clocks and multiple downstream loads, maintaining signal integrity through differential buffering. The 38-TSSOP package allows for compact integration in space-constrained high-performance electronic designs.
