SL23EP09ZI-1

Clock Generators, PLLs, Frequency Synthesizers Overview

The SL23EP09ZI-1 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 frequency range of 10 to 220 MHz and supports a wide power supply voltage of 2.5 V to 3.3 V. It features an on-chip PLL that locks to the input clock via internal feedback from the CLKOUT pin. The component includes two clock driver banks with four outputs each, controlled by select pins S1 and S2. It is available in standard and high-drive options and comes in 16-pin SOIC and TSSOP packages.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature grade. The 'ZI' suffix indicates Industrial grade (-40°C to +85°C) and TSSOP packaging. Confirm availability status as this product may be discontinued or restricted. Ensure compliance with moisture sensitivity levels and handling requirements specified in the datasheet before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select the SL23EP09ZI-1 for applications requiring low skew and jitter clock distribution. Choose the standard drive version for lower power consumption at moderate frequencies. Use the high-drive variant if higher load capacitance or wider frequency ranges are needed. Ensure the operating voltage matches the 2.5V or 3.3V supply rails. Verify thermal performance under maximum load conditions.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The SL23EP09 series is part of Silicon Laboratories' timing portfolio, specifically designed as low-power, low-jitter zero-delay buffers.
