ICS2304NZGI-1

Clock Buffers, Drivers Overview

The ICS2304NZGI-1 is a low skew, low jitter PCI/PCI-X clock driver designed for high-speed signal distribution in applications operating from 0 to 140 MHz. It accepts one clock input and distributes it to four buffered outputs with less than 100 ps skew between output pins. The device operates at a supply voltage of 3.3 V ±10% and is characterized for the industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum propagation delay of 3.8 ns, cycle-to-cycle jitter of 200 ps, and dynamic supply current of 37 mA at 66.67 MHz.

Clock Buffers, Drivers Feature Summary

• Low skew performance with less than 100 ps skew between outputs
• Supports frequencies up to 140 MHz for PCI/PCI-X applications
• Industrial temperature range (-40°C to +85°C)
• Single-ended HCMOS compatible inputs and outputs

Clock Buffers, Drivers Applications

• PCI/PCI-X bus architectures
• High-speed data acquisition systems
• Industrial control networks

Clock Buffers, Drivers Procurement Notes

Verify that the specific order includes the 'I' suffix to confirm the industrial temperature rating (-40°C to +85°C). Confirm RoHS compliance by checking for the 'LF' suffix if lead-free packaging is required. Note that non-green parts have an end-of-life date of May 13, 2010; ensure current stock meets environmental standards.

Clock Buffers, Drivers Selection Notes

Select this component when distributing a single clock source to four loads requiring tight timing alignment. Ensure the system load capacitance does not exceed specifications to maintain the <100 ps skew guarantee. Verify that the 3.3V supply voltage aligns with the target logic levels.

Clock Buffers, Drivers Part Context

This part belongs to the ICS2304 series of low skew buffers manufactured by Integrated Device Technology (IDT), now part of Renesas Electronics. The 'NZG' indicates the package type and lead-free status, while 'I' specifies the industrial temperature grade. It serves as a fan-out buffer for clock signals in legacy and industrial computing hardware.

Clock Buffers, Drivers Replacement Considerations

Compatible replacements within the same family include the ICS2304NZG-1 (commercial temperature) or variants with different suffixes for tape and reel packaging (e.g., ICS2304NZGI-1T). Cross-vendor equivalents require matching the 1:4 fan-out ratio, 3.3V operation, and low skew specifications.
