SL2309ZI-1T

Clock Generators, PLLs, Frequency Synthesizers Overview

The SL2309ZI-1T is a low skew, low jitter Zero Delay Buffer (ZDB) manufactured by Skyworks Solutions Inc. It generates up to nine clock outputs from one reference input for high-speed distribution. The device operates within a 10 to 140 MHz frequency range and utilizes a 3.3 V power supply. Key electrical parameters include a maximum cycle-to-cycle jitter of 140 ps and an output-to-output skew of 150 ps. Power dissipation reaches 44 mA at 133 MHz. The component is housed in a 16-pin TSSOP package and supports industrial temperature grades.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel shipping format associated with the 'T' designation. Confirm that the Industrial grade (-I) variant meets the required ambient operating temperature range of -40°C to 85°C. Ensure the design accounts for the manufacturer's recommendation against using this part in new designs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the standard drive option when load capacitance is limited to 15 pF and frequencies do not exceed 100 MHz. Choose the High-Drive version if operation requires frequencies up to 140 MHz with 15 pF loads. Verify that all output pins are loaded equally to maintain specified skew and zero delay performance characteristics.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the SL2309 family of timing products originally developed by Silicon Laboratories. The product line includes variants with different drive strengths and packaging options. The SL2309 series is designed for applications requiring precise clock distribution with minimal jitter and skew across multiple output channels.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

The SL23EP09 provides extended frequency operation up to 220 MHz and supports a wider voltage range. Consider this alternative only if higher frequency capabilities or 2.5V operation are required.
