SL2304NZZI-1T

Clock Buffers, Drivers Overview

The SL2304NZZI-1T is a low skew, low jitter fanout buffer manufactured by Skyworks Solutions Inc. It operates from DC to 140 MHz with a 3.3V +/-10% supply voltage. The device provides one input to four output clock distribution and features an Output Enable (OE) control function. It is housed in an 8-pin TSSOP package and supports the Industrial temperature range of -40°C to +85°C. Key electrical characteristics include a typical propagation delay of 2.5 ns, output-to-output skew of 60 ps, and power dissipation of 14 mA at 66 MHz.

Clock Buffers, Drivers Feature Summary

• DC to 140 MHz operating frequency range
• Low output clock skew: 60 ps-typ (Industrial grade)
• Low propagation delay: 2.5 ns-typ
• One input to four output fanout buffer drivers

Clock Buffers, Drivers Applications

• General Purpose PCI/PCI-X Clock Buffer
• Printers, MFPs and Digital Copiers
• Routers, Switches and Servers
• Datacom and Telecom

Clock Buffers, Drivers Procurement Notes

Verify that the component matches the specific OE logic configuration required for the design, as the 'Z' suffix indicates a distinct Output Enable implementation compared to non-Z variants. Confirm the tape and reel shipping format aligns with automated assembly requirements. Ensure the industrial temperature grade (-40°C to +85°C) meets the environmental specifications of the target system.

Clock Buffers, Drivers Selection Notes

Select this part for applications requiring low skew and jitter clock distribution up to 140 MHz. The SL2304NZZI-1T is suitable for designs needing the specific high-active-low-disable OE logic state. For higher frequency requirements up to 220 MHz or improved drive options, consider the SL23EP04NZ product family instead.

Clock Buffers, Drivers Part Context

This component belongs to the SL2304NZ series of low skew, low jitter fanout buffers. The 'ZI' suffix denotes the Industrial temperature grade (-40°C to +85°C), while the trailing 'T' indicates Tape and Reel packaging. The 'Z' in the base model number signifies a specific Output Enable logic implementation where outputs go to High-Z when disabled.

Clock Buffers, Drivers Replacement Considerations

For systems requiring operation up to 220 MHz, improved skew, and broader voltage support (2.5V to 3.3V), the SL23EP04NZ is the recommended successor. Verify OE logic compatibility if substituting with other SL2304NZ variants.

Clock Buffers, Drivers FAQ

What is the difference between the SL2304NZ-1 and SL2304NZ-1Z regarding the Output Enable function?

When OE=0, the SL2304NZ-1 outputs are disabled and driven to Logic Low. In contrast, the SL2304NZ-1Z outputs enter a High-Z state.

What is the maximum operating frequency of the SL2304NZZI-1T?

The device operates from DC to 140 MHz with a 15pF load, or up to 100 MHz with a 30pF load.

What decoupling capacitor is recommended for the VDD pin?

A 0.1μF decoupling capacitor must be used between the VDD and GND pins, placed as close to the VDD pin as possible on the component side of the PCB.
