CY2309NZSXC-1HT

Clock Buffers, Drivers Overview

The CY2309NZSXC-1HT is a nine-output, non-zero delay buffer manufactured by Infineon Technologies. It operates on a single 3.3 V supply (3.0 V to 3.6 V) and supports clock frequencies from 2 MHz to 133.33 MHz. The device features one input and nine outputs with a propagation delay of up to 9.2 ns and output-to-output skew under 250 ps. Designed for low power consumption, it draws less than 32 mA at 66.6 MHz with unloaded outputs. It is housed in a space-saving 16-pin SOIC package and is supplied in tape and reel format.

Clock Buffers, Drivers Feature Summary

• Nine-output fanout buffer supporting frequencies up to 133.33 MHz
• Low power consumption: <32 mA at 66.6 MHz with unloaded outputs
• Output-to-output skew less than 250 ps
• Multiple VDD and GND pins for noise and EMI reduction

Clock Buffers, Drivers Applications

• Mobile PC systems requiring high-speed clock distribution
• Desktop PC systems with SDRAM support
• Driving two DIMMs or four SO-DIMMs
• External feedback to chipset phase-locked loops (PLL)

Clock Buffers, Drivers Procurement Notes

Verify the specific ordering suffix 'T' confirms the Tape and Reel packaging format as specified in the datasheet. Confirm that the commercial temperature grade (C) aligns with the required operating range of 0°C to 70°C. Ensure the 16-SOIC package dimensions match the PCB footprint requirements.

Clock Buffers, Drivers Selection Notes

Select this component when a non-zero delay buffer is required for distributing clocks to multiple memory modules. Ensure the load capacitance does not exceed 30 pF for frequencies below 100 MHz or 15 pF for frequencies between 100 MHz and 133.33 MHz. Verify that the system can accommodate the 9.2 ns maximum propagation delay.

Clock Buffers, Drivers Part Context

This part belongs to the CY2309NZ family of nine-output buffers. It serves as a low-cost solution for mobile and desktop PC architectures. The device is designed to optimize power and reduce electromagnetic interference through its multi-supply pin configuration.

Clock Buffers, Drivers Replacement Considerations

The CY2309NZSC-1H is a tube-packaged equivalent within the same family. Other variants include industrial temperature versions (CY2309NZSXI-1HT). Verify compatibility if substituting with different package types or temperature grades.
