SL23EP05BSI-1HT

Clock Generators, PLLs, Frequency Synthesizers Overview

The SL23EP05BSI-1HT is a low skew, low jitter Zero Delay Buffer (ZDB) manufactured by Skyworks Solutions Inc. It features an on-chip PLL that locks to the input clock at CLKIN and provides feedback internally from the CLKOUT pin. The device operates within a frequency range of 10 to 220 MHz at 3.3 V and up to 180 MHz at 2.5 V for the high-drive version. It accepts one reference input and produces five buffered outputs organized as 4+1. The component supports SpreadThru™ technology for spread spectrum clocking and includes a power-down mode with less than 10 μA current draw when the input frequency is below 2.0 MHz.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

• Low output-to-output skew of 30 ps typical and product-to-product skew of 60 ps typical
• SpreadThru™ PLL capability allows direct passing of modulated spread spectrum clock signals without degradation
• High-drive option enables operation up to 220 MHz at 3.3 V with controlled impedance levels

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. The SL23EP05BSI-1HT designation indicates a Tape & Reel shipping format and Industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status directly with the supplier or datasheet before procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component for high-speed clock distribution requiring minimal skew and jitter. Ensure the load capacitance matches the drive strength requirements; the high-drive version supports higher frequencies up to 220 MHz at 3.3 V. Verify that the application requires the specific industrial temperature range and tape-and-reel packaging associated with the BSI-1HT suffix.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the SL23EP05 family of Zero Delay Buffers. The 'B' in the suffix typically denotes the Tape & Reel packaging variant, while 'SI' indicates the Industrial temperature grade (-40°C to +85°C), and '1H' specifies the High-Drive strength option. The device is marked as Not Recommended for New Designs by Silicon Laboratories.
