IDT2309NZ-1HDC8

Clock Buffers, Drivers Overview

The IDT2309NZ-1HDC8 is a nine-output, 3.3V clock buffer manufactured by Renesas Electronics Corporation (formerly IDT). It distributes high-speed clocks in mobile and desktop PC systems with SDRAM support. The device operates at frequencies from DC to 133.33MHz with an input-to-output propagation delay of 8.7ns and output-to-output skew under 250ps. It consumes less than 32mA at 66.6MHz with unloaded outputs. The component is housed in a 16-pin SOIC package and supports commercial temperature ranges.

Clock Buffers, Drivers Feature Summary

• One input to nine output buffer/driver configuration
• Supports two DIMMs or four SO-DIMMs with one additional output for external PLL feedback
• Low power consumption: less than 32mA at 66.6MHz with unloaded outputs
• Output-to-output skew less than 250ps

Clock Buffers, Drivers Applications

• Mobile PC systems
• Desktop PC systems with SDRAM support
• Clock distribution for memory modules

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm the package type and temperature range. The 'DCG' suffix indicates a green-compliant 16-pin SOIC package. Confirm RoHS compliance status as non-green parts have reached end-of-life dates per PDN U-09-01.

Clock Buffers, Drivers Selection Notes

Select this component when a single-clock source must drive multiple memory loads with low skew requirements. Ensure the load capacitance does not exceed 30pF for frequencies below 100MHz or 15pF for frequencies between 100MHz and 133.33MHz. Verify that the system voltage remains within the 3V to 3.6V supply range.

Clock Buffers, Drivers Part Context

This part belongs to the IDT2309 series of nine-output 3.3V clock buffers. The 'NZ' designation identifies it as a standard buffer variant. The '1H' suffix denotes a high-drive version with faster rise and fall times compared to base parts. The 'DCG8' suffix specifies the tape and reel packaging for the green-compliant SOIC package.

Clock Buffers, Drivers Replacement Considerations

Check for equivalent nine-output clock buffers from other manufacturers if the IDT2309NZ-1HDC8 is unavailable. Ensure replacement parts match the 16-pin SOIC footprint and support the required 133.33MHz frequency with similar skew specifications.
